Description
I/O Pin State – returns the current state of the I/O pin (0/1) when read
A write affects the I/0 pin directly if DIR=1 and FME=0
Direction – controls if the I/O pin is an input or an output
0 input
1 output
Inversion – controls if the I/O pin is inverted or not. Applies to both pin directions
(read and write).
0 not inverted
1 inverted
Function Mapping Enable – Enables function mapping of the pin. A function
mapping code must be set in GPIO configuration register [8:15]. The pin will carry
out the assigned operation and is not accessible anymore as GPIO.
0 disable function mapping
1 enable function mapping
