Read: Anytime. Write: Anytime.
This register configures port pins PAD[15:0] as either input or output.
If a data direction bit is 0 (pin configured as input), then a read value on PTADx depends on the associated
ATDDIEN0(1) bit. If the associated ATDDIEN0(1) bit is set to 1 (digital input buffer is enabled), a read
on PTADx returns the value on port AD pin. If the associated ATDDIEN0(1) bit is set to 0 (digital input
buffer is disabled), a read on PTADx returns a 1.
