P3DDR is initialized to H'00 (bits 5 to 0) by a power-on reset, and in hardware standby mode. It retains its prior state after
a manual reset*, and in software standby mode. As the SCI is initialized, the pin states are determined by the P3DDR and
P3DR specifications.
Note:
* Manual reset is only supported in the H8S/2357 ZTAT.

P3DR is an 8-bit readable/writable register that stores output data for the port 3 pins (P3
5
to P3
0
).
Bits 7 and 6 are reserved; they return an undetermined value if read, and cannot be modified.
P3DR is initialized to H'00 (bits 5 to 0) by a power-on reset, and in hardware standby mode. It retains its prior state after a

PORT3 is an 8-bit read-only register that shows the pin states. Writing of output data for the port 3 pins (P3
5
to P3
0
) must
always be performed on P3DR.
Bits 7 and 6 are reserved; they return an undetermined value if read, and cannot be modified.
If a port 3 read is performed while P3DDR bits are set to 1, the P3DR values are read. If a port 3 read is performed while
P3DDR bits are cleared to 0, the pin states are read.
After a power-on reset and in hardware standby mode, PORT3 contents are determined by the pin states, as P3DDR and
P3DR are initialized. PORT3 retains its prior state after a manual reset*, and in software standby mode.
Note:
* Manual reset is only supported in the H8S/2357 ZTAT.
