Port C Data Register (PCDR)
PCDR is an 8-bit readable/writable register that stores output data for the port C pins (PC
PCDR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its prior
state after a manual reset, and in software standby mode.
Port C Register (PORTC)
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 (PC
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 power-on 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 after a manual reset, and
in software standby mode.

Modes 3 and 7
Setting a PCDDR bit to 1 makes the corresponding port C pin an output port, while clearing
the bit to 0 makes the pin an input port.
Note: Modes 3 and 7 cannot be used in the H8S/2240.
