Ya’ll gone make me act a fool, up in here, up in here
Ya’ll gone make me loose my cool, up in here up in here,
Ya’ll gone make me bust a smack, up in here, up in here,
Ya’ll gone make my fingers snap, up in here, up in here,
Why should I battle a crusty old man,
When you can’t even defeat a little weak Peter Pan,
Ya lucky this is only a beatbox battle,
Cause in a real battle I make ya feel rattled,
Look at him, he only got one planet,
I got the whole Galaxy under my dependence,
You’re gonna beg when you bleed and die,
As you realize destiny arrived,
Ya’ll gone make me + Beatbox
Ya’ll gone make me + Beatbox
Ya’ll gone make me + Beatbox
Ya’ll gone make me + Beatbox

Let me show you how to scratch it

Either way, destiny still arrives "

An interrupt can be generated for every GPIO pin in four scenarios:
• Level High: the GPIO pin is a logical 1
• Level Low: the GPIO pin is a logical 0
• Edge High: the GPIO has transitioned from a logical 0 to a logical 1
• Edge Low: the GPIO has transitioned from a logical 1 to a logical 0
The level interrupts are not latched. This means that if the pin is a logical 1 and the level high interrupt is active, it will
become inactive as soon as the pin changes to a logical 0. The edge interrupts are stored in the INTR register and can be
cleared by writing to the INTR register.
There are enable, status, and force registers for three interrupt destinations: proc 0, proc 1, and dormant_wake. For proc
0 the registers are enable (PROC0_INTE0), status (PROC0_INTS0), and force (PROC0_INTF0). Dormant wake is used to
wake the ROSC or XOSC up from dormant mode. See Section 6.5.6.2 for more information on dormant mode.
There is an interrupt output for each combination of IO bank, IRQ destination, and security domain. In total there are
twelve such outputs:
• IO Bank 0 to dormant wake (Secure and Non-secure)
• IO Bank 0 to proc 0 (Secure and Non-secure)
• IO Bank 0 to proc 1 (Secure and Non-secure)
• IO QSPI to dormant wake (Secure and Non-secure)
• IO QSPI to proc 0 (Secure and Non-secure)
• IO QSPI to proc 1 (Secure and Non-secure)
Each interrupt output has its own array of enable registers (INTE) that configures which GPIO events cause the interrupt
to assert. The interrupt asserts when at least one enabled event occurs, and de-asserts when all enabled events have
been acknowledged via the relevant INTR register.
This means the user can watch for several GPIO events at once.
Summary registers can be used to quickly check for pending GPIO interrupts. See IRQSUMMARY_PROC0_NONSECURE0
for an example.

 CAUTION
Under certain conditions, pull-down does not function as expected. For more information, see RP2350-E9.
Each GPIO is connected off-chip via a pad. Pads are the electrical interface between the chip’s internal logic and
external circuitry. They translate signal voltage levels, support higher currents and offer some protection against
electrostatic discharge (ESD) events. You can adjust pad electrical behaviour to meet the requirements of external
circuitry in the following ways:
• Output drive strength can be set to 2mA, 4mA, 8mA or 12mA.
• Output slew rate can be set to slow or fast.
• Input hysteresis (Schmitt trigger mode) can be enabled.
• A pull-up or pull-down can be enabled, to set the output signal level when the output driver is disabled.
• The input buffer can be disabled, to reduce current consumption when the pad is unused, unconnected or
connected to an analogue signal.
An example pad is shown in Figure 42.

Figure 42. Diagram of
a single IO pad.
The pad’s Output Enable, Output Data and Input Data ports connect, via the IO mux, to the function controlling the pad.
All other ports are controlled from the pad control register. You can use this register to disable the pad’s output driver by
overriding the Output Enable signal from the function controlling the pad. See GPIO0 for an example of a pad control
register.
Both the output signal level and acceptable input signal level at the pad are determined by the digital IO supply (IOVDD).
IOVDD can be any nominal voltage between 1.8V and 3.3V, but to meet specification when powered at 1.8V, the pad
input thresholds must be adjusted by writing a 1 to the pad VOLTAGE_SELECT registers. By default, the pad input thresholds
are valid for an IOVDD voltage between 2.5V and 3.3V. Using a voltage of 1.8V with the default input thresholds is a safe
operating mode, but it will result in input thresholds that don’t meet specification.
 WARNING
Using IOVDD voltages greater than 1.8V, with the input thresholds set for 1.8V may result in damage to the chip.
Pad input threshold are adjusted on a per bank basis, with separate VOLTAGE_SELECT registers for the pads associated with
the User IO bank (IO Bank 0) and the QSPI IO bank. However, both banks share the same digital IO supply (IOVDD), so
both register should always be set to the same value.
Pad register details are available in Section 9.11.3, “Pad Control - User Bank” and Section 9.11.4, “Pad Control - QSPI
Bank”.

[…] For each pad, only the pull-up or the pull-down resistor can be enabled at any given time. It is impossible to enable both
simultaneously. Instead, if you set both the GPIO0.PDE and GPIO0.PUE bits simultaneously then you enable bus keeper
mode, where the pad is:
• Pulled up when its input is high.
• Pulled down when its input is low.
When the output buffer is disabled, and the pad is not driven by any external source, this mode weakly retains the pad’s
current logical state. The pad does not float to mid-rail.
Bus keeper mode relies on control logic in the switched core domain, so does not function when the core is powered
down. Rather, powering down the core when bus keeper mode is enabled latches the current output controls (pull-up or
pull-down) in the pad isolation latches, as described in Section 9.7.
9.7. Pad isolation latches
RP2350 features extended low-power states that allow all internal logic, with the exception of POWMAN and some
CoreSight debug logic, to fully power down under software control. This includes powering down all peripherals, the IO
muxing, and the pad control registers, which brings with it the risk that pad signals may experience unwanted
transitions when entering and exiting low-power states.
To ensure that pad states are well-defined at all times, all signals passing from the switched core power domain to the
pads pass through isolation latches. In normal operation, the latches are transparent, so the pads are controlled fully by
logic inside the switched core power domain, such as UARTs or the processors. However, when the ISO bit for each pad
is set (e.g. GPIO0.ISO) or the switched core domain is powered down, the control signals currently presented to that pad
are latched until the isolation is disabled. This includes the output enable state, output high/low level, and pull-up/pulldown resistor enable. The input signal from the pad back into the switched core domain is not isolated.
Consequently, when switched core logic is powered down, all Bank 0 and Bank 1 pads maintain the output state they
held immediately before the power down, unless overridden by always-on logic in POWMAN. When the switched core
power domain powers back up, all the GPIO ISO bits reset to 1, so the pre-power down state continues to be maintained
until user software starts up and clears the ISO bit to indicate it is ready to use the pad again. Pads whose IO muxing
has not yet been set up can be left isolated indefinitely, and will maintain their pre-power down state.
when software has finished setting up the IO muxing for a given pad, and the peripheral that is to be muxed in, the ISO
bit should be cleared. At this point the isolation latches will become transparent again: output signals passing through
the IO muxing block are now reflected in the pad output state, so peripherals can communicate with the outside world.
This process allows the switched core domain to be power cycled without causing any transitions on the pad outputs
that may interfere with the operation of external hardware connected to the pads.
 NOTE
Non-SDK applications ported from RP2040 must clear the ISO bit before using a GPIO, as this feature was not
present on RP2040. The SDK automatically clears the ISO bit when gpio_set_function() is called.
The isolation latches themselves are reset by the always-on power domain reset, namely any one of:
• Power-on reset
• Brownout reset
• RUN pin being asserted low
• SW-DP CDBGRSTREQ
• RP-AP rescue reset
The latches reset to the reset value of the signal being isolated. For example, on Bank 0 GPIOs, the input enable control
RP2350 Datasheet
9.7. Pad isolation latches 596
(GPIO0.IE) resets to 0 (input-disabled), so the isolation latches for these signals also take a reset value of 0. Resetting
the isolation latch forces the pad to assume its reset state even if it is currently isolated.
The ISO control bits (e.g. GPIO0.ISO) are reset by the top-level switched core domain isolation signal, which is asserted
by POWMAN before powering down the switched core domain and de-asserted after it is powered up. This means that
entering and exiting a sleep state where the switched core domain is unpowered leaves all GPIOs isolated after power
up; you can then re-engage them individually. The ISO control bits are not reset by the PADS register block reset driven
by the RESETS control registers: resetting the PADS register block returns non-isolated pads to their reset state, but has
no effect on isolated pads
