Default after reset (PUC/POR)
NOTES: 1. N/A: Not available or not applicable.
2. X: Don’t care.
3. Setting the CAPD.x bit disables the output driver as well as the input Schmitt trigger to prevent parasitic cross currents when applying
analog signals. Selecting the CAx input pin to the comparator multiplexer with the P2CAx bits automatically disables the input buffer
for that pin, regardless of the state of the associated CAPDx bit.

for that pin, regardless of the state of the associated CAPD.x bit.
4. If the pin XOUT/P2.7/CA7 is used as an input a current can flow until P2SEL.7 is cleared due to the oscillator output driver connection
to this pin after reset.
