CAPDx Bits
7-0 Comparator_A port disable. These bits individually disable the input buffer
for the pins of the port associated with Comparator_A. For example, the
CAPDx bits can be used to individually enable or disable each P1.x pin
buffer. CAPD0 disables P1.0, CAPD1 disables P1.1, etc.
0
The input buffer is enabled.
1 The input buffer is disabled.
