Description

RW MODE

Mode

Disabled

Disabled. Pin specified by PSEL will not be acquired by the

GPIOTE module.

Event

Event mode

The pin specified by PSEL will be configured as an input and

the IN[n] event will be generated if operation specified in

POLARITY occurs on the pin.

Task

Task mode

The GPIO specified by PSEL will be configured as an output

and triggering the SET[n], CLR[n] or OUT[n] task will

perform the operation specified by POLARITY on the pin.

When enabled as a task the GPIOTE module will acquire the

pin and the pin can no longer be written as a regular output

pin from the GPIO module.

RW PSEL

[0..31]

GPIO number associated with SET[n], CLR[n] and OUT[n]

tasks and IN[n] event

RW POLARITY

When In task mode: Operation to be performed on output

when OUT[n] task is triggered. When In event mode:

Operation on input that shall trigger IN[n] event.

None

Task mode: No effect on pin from OUT[n] task. Event mode:

no IN[n] event generated on pin activity.

LoToHi

Task mode: Set pin from OUT[n] task. Event mode: Generate

IN[n] event when rising edge on pin.

HiToLo

Task mode: Clear pin from OUT[n] task. Event mode:

Generate IN[n] event when falling edge on pin.

Toggle

Task mode: Toggle pin from OUT[n]. Event mode: Generate

IN[n] when any change on pin.

RW OUTINIT

When in task mode: Initial value of the output when the

GPIOTE channel is configured. When in event mode: No

effect.

Low

Task mode: Initial value of pin before task triggering is low
