The General-Purpose Input/Output (GPIO)s have user-configurable features.
The features are provided in the following list:
- Configurable output drive strength
- Internal pull-up and pull-down resistors
- Wake-up from high- or low-level triggers on all pins
- Trigger interrupt on state changes on any pin
- All pins can be used by the Programmable Peripheral Interconnect (PPI) task/event system
- One or more GPIO output can be controlled through PPI and GPIOTE channels
- All pins can be individually mapped to interface blocks for layout's flexibility
- GPIO state changes captured on SENSE signal can be stored by LATCH register
- Support for secure and non-secure attributes for pins in conjunction with the system
protection unit

nRF9160 Product Specification.
