Port C Data Direction Register (PCDDR): PCDDR is an 8-bit write-only register that can select
input or output for each pin in port C.
When bits in PCDDR are set to 1, pins PC
pins PC
corresponding pins become input pins.
PCDDR is a write-only register. Its value cannot be read. All bits return 1 when read.
PCDDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting, so if a PCDDR bit is set to 1, the corresponding pin maintains its
output state in software standby mode.
Port C Data Register (PCDR): PCDR is an 8-bit readable/writable register that stores data for
pins PC
When a bit in PCDDR is set to 1, if port C is read the value of the corresponding PCDR bit is
returned directly. When a bit in PCDDR is cleared to 0, if port C is read the corresponding pin
level is read.
PCDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
