17.1.7 Port G Control Register (PGCR)
Port G Control Register (PGCR) is a 16-bit read/write register that selects the pin functions and
the input pull-up MOS control. PGCR is initialized to H'AAAA (in case of ASEMD0 = 1) or
H'A800 (in case of ASEMD0 = 0) by power-on resets; however, it is not initialized by manual
resets, in standby mode, or in sleep mode.
