Section 9 I/O Ports
Port D Data Register (PDDR)
PDDR is an 8-bit readable/writable register that stores output data for the port D pins (PD7 to
PD0).
PDDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
Port D Register (PORTD)
Note: * Determined by state of pins PD7 to PD0.
PORTD is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port D pins (PD7 to PD0) must always be performed on PDDR.
If a port D read is performed while PDDDR bits are set to 1, the PDDR values are read. If a port D
read is performed while PDDDR bits are cleared to 0, the pin states are read.
After a reset and in hardware standby mode, PORTD contents are determined by the pin states, as
PDDDR and PDDR are initialized. PORTD retains its prior state in software standby mode.
