Port C Data Direction Register (PCDDR)
PCDDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port C. PCDDR cannot be read; if it is, an undefined value will be read.
PCDDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode. The OPE bit in SBYCR is used to select whether the address output pins
retain their output state or become high-impedance when a transition is made to software standby
mode.
• Modes 4 and 5
• Mode 6 *
• Mode 7 *
Note: * Modes 6 and 7 are not available in the ROMless versions.

Bit
Initial value :
R/W
The corresponding port C pins are address outputs irrespective of the value of the PCDDR bits.
Setting PCDDR bits to 1 makes the corresponding port C pin address outputs, while clearing
the bits to 0 makes the pins input ports.
Setting PCDDR bits to 1 makes the corresponding port C pins an output ports, while clearing
the bits to 0 makes the pins input ports.
