GPIO 1 Input Polarity Control (used in conjunction with
GPIOSticky) and Output Type Control.
When configured as a level-sensitive input:
0 = inverted
1 = not inverted (default)
When configured as an edge-sensitive input:
0 = falling-edge triggered
1 = rising-edge triggered
When configured as an output:
0 = push-pull (CMOS)
1 = open drain (default)
