The port G control register (PGCR) is a readable and writeable 16-bit register used to select pin
functions. PGCR is initialized to H'AAAA (ASEMD0 = 1) or H'A200 (ASEMD0 = 0) at power-on
reset, but it is not initialized by manual resets or in the standby mode or sleep mode.

These bits are used to select pin functions and input pull-up MOS control settings. In the PG1 and
PG0 modes, bit 3 (PG1MD1) is used to select between “other function” and “port input.” When
the port input setting is selected (PG1MD1 = 1), pull-up MOS on-off selection is performed using
bit 2 (PG1MD0) in the PG1 mode and bit 0 (PG0MD0) in the PG0 mode.
