6.9 GPIOTE — GPIO tasks and events

The GPIO tasks and events (GPIOTE) module provides functionality for accessing GPIO pins using tasks and

events. Each GPIOTE channel can be assigned to one pin.

A GPIOTE block enables GPIOs to generate events on pin state change which can be used to carry out tasks

through the PPI system. A GPIO can also be driven to change state on system events using the PPI system.

Low power detection of pin state changes is possible when in System ON or System OFF.

GPIOTE

Table 38: GPIOTE properties

Up to three tasks can be used in each GPIOTE channel for performing write operations to a pin. Two tasks

are fixed (SET and CLR), and one (OUT) is configurable to perform following operations:

• Set

• Clear

• Toggle
