The port G control register (PGCR) is a 16-bit readable/writable register that selects the pin
functions. PGCR is initialized to H'AAAA (ASEMD0 = 1) or H'A200 (ASEMD0 = 0) by a power-
on reset, but is not initialized by a manual reset, in standby mode, or in sleep mode.
Bits 15 and 14—PG7 Mode 1 and 0 (PG7MD1, PG7MD0)
Bits 13 and 12—PG6 Mode 1 and 0 (PG6MD1, PG6MD0)
Bits 11 and 10—PG5 Mode 1 and 0 (PG5MD1, PG5MD0)
Bits 9 and 8—PG4 Mode 1 and 0 (PG4MD1, PG4MD0)
Bits 7 and 6—PG3 Mode 1 and 0 (PG3MD1, PG3MD0)
Bits 5 and 4—PG2 Mode 1 and 0 (PG2MD1, PG2MD0)
Bits 3 and 2—PG1 Mode 1 and 0 (PG1MD1, PG1MD0)
Bits 1 and 0—PG0 Mode 1 and 0 (PG0MD1, PG0MD0)
These bits select the pin functions and perform input pull-up MOS control.
