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:

 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

 All pins can be individually configured to carry serial interface or quadrature demodulator

signals

HW debug and flash programming of Module:

The Module support the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful

mechanism for non-intrusive debugging of program code. Breakpoints, single stepping, and

instruction trace capture of code execution flow are part of this support.
