7.3 General Purpose I/O
The general purpose I/O is organized as one port enabling access and control of the 32 available GPIO pins through
one port. Each GPIO can be accessed individually with the following user configurable features:
one port. Each GPIO can be accessed individually with the following user configurable features:
Input/output direction
Output drive strength
Internal pull-up and pull-down resistors
Wake-up from high or low level triggers on all pins
Trigger interrupt on all pins
All pins can be used by the PPI task/event system; the maximum number of pins that can be interfaced
through the PPI at the same time is limited by the number of GPIOTE channels
through the PPI at the same time is limited by the number of GPIOTE channels
All pins can be individually configured to carry serial interface or quadrature demodulator signals
