1 The pin is connected to CA1
P2CA0 Bit 2 Pin to CA0. This bit selects the CA0 pin function.
0 The pin is not connected to CA0
1 The pin is connected to CA0
CAF Bit 1 Comparator_A output filter
0 Comparator_A output is not filtered

Comparator_A port disable. These bits individually disable the input buffer
for the pins of the port associated with Comparator_A. For example, if CA0
is on pin P2.3, the CAPDx bits can be used to individually enable or
disable each P2.x pin buffer. CAPD0 disables P2.0, CAPD1 disables P2.1,
etc.
0 The input buffer is enabled.
1 The input buffer is disabled.
