Port C Data Register (PCDR)
PCDR is an 8-bit readable/writable register that stores output data for the port C pins (PC7 to
PC0).
PCDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
Port C Register (PORTC)
Note: * Determined by state of pins PC7 to PC0.
PORTC is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port C pins (PC7 to PC0) must always be performed on PCDR.
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.
After a reset and in hardware standby mode, PORTC contents are determined by the pin states, as
PCDDR and PCDR are initialized. PORTC retains its prior state in software standby mode.
