The port C control register (PCCR) is a 16-bit readable/writable register that selects the pin
functions. PCCR is initialized to H'AAAA by a power-on reset, but is not initialized by a manual
reset, in standby mode, or in sleep mode.
Bits 15 and 14—PC7 Mode 1 and 0 (PC7MD1, PC7MD0)
Bits 13 and 12—PB6 Mode 1 and 0 (PC6MD1, PC6MD0)
Bits 11 and 10—PC5 Mode 1 and 0 (PC5MD1, PC5MD0)
Bits 9 and 8—PC4 Mode 1 and 0 (PC4MD1, PC4MD0)
Bits 7 and 6—PC3 Mode 1 and 0 (PC3MD1, PC3MD0)
Bits 5 and 4—PC2 Mode 1 and 0 (PC2MD1, PC2MD0)
Bits 3 and 2—PC1 Mode 1 and 0 (PC1MD1, PC1MD0)
Bits 1 and 0—PC0 Mode 1 and 0 (PC0MD1, PC0MD0)
These bits select the pin functions and perform input pull-up MOS control.
