If a port C read is performed while PCDDR bits are set to
1, the PCDR values are read. If a port C read is
performed while PCDDR bits are cleared to 0, the pin
states are read.

Note: * Determined by the states of pins PC7 to PC0.
9.8.4 Port C Pull-Up MOS Control Register (PCPCR)
PCPCR controls the on/off state of input pull-up MOS of port C.
Bit Bit Name Initial Value R/W Description
7 PC7PCR 0 R/W
6 PC6PCR 0 R/W
5 PC5PCR 0 R/W
4 PC4PCR 0 R/W
3 PC3PCR 0 R/W
2 PC2PCR 0 R/W
1 PC1PCR 0 R/W
When a pin function is specified to an input port, setting
the corresponding bit to 1 turns on the input pull-up MOS
for that pin.
