Port 3 Data Direction Register (P3DDR)
P3DDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port 3. Bits 7 and 6 are reserved. P3DDR cannot be read; if it is, an undefined value will be
read.
Setting a P3DDR bit to 1 makes the corresponding port 3 pin an output pin, while clearing the bit
to 0 makes the pin an input pin.
P3DDR is initialized to H'00 (bits 5 to 0) by a reset, and in hardware standby mode. It retains its
prior state in software standby mode. As the SCI is initialized, the pin states are determined by the
P3DDR and P3DR specifications.
Port 3 Data Register (P3DR)
P3DR is an 8-bit readable/writable register that stores output data for the port 3 pins (P3
Bits 7 and 6 are reserved; they return an undefined value if read, and cannot be modified.
P3DR is initialized to H'00 (bits 5 to 0) by a reset, and in hardware standby mode. It retains its
prior state in software standby mode.
