PMRST_I/O_CTRL
PMRST I/O Control.
This bit is set to 1 to make
PMRST an output.
Reserved.
These bits must be written to their reset
default value (000).
GPIO Interrupt Active State.
0 = report received value unchanged (level = input pin
value, positive edge = 1 when signal rises).
1 = invert received value (level = invert input pin value,
positive edge = 0 when detected).
GPIO Interrupt Type.
0 = positive edge; 1 = level.
