4.3.5 Port mode control registers 0, 2 (PMC0, PMC2)
These registers set the digital I/O/analog input in 1-bit units.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears these registers to FFH.

Caution 1. Select input mode by using port mode registers 0, 2 (PM0, PM2) for the ports which are set by the
PMC0, PMC2 registers as analog input.
Caution 2. Be sure to set bits that are not mounted to their initial values.
