Value Description
PFUNC20 bit determines if VCTL1 pin functions as GPIO.
0 Pin functions normally.
1 Pin functions as GPIO pin.
0 Reserved. The reserved bit location is always read as 0. A
value written to this field has no effect.
PFUNC10 bit determines if VDATA[19–10] pins function as
GPIO.
0 Pins function normally.
1 Pins function as GPIO pin.
0 Reserved. The reserved bit location is always read as 0. A
value written to this field has no effect.
PFUNC0 bit determines if VDATA[9–0] pins function as
GPIO.
0 Pins function normally.
1 Pins function as GPIO pin.
