Section 10 I/O Ports
Notes: 1. Mode 3 is not supported in H8S/2678 Group.
10.1
Port 1 is an 8-bit I/O port that also has other functions. The port 1 has the following registers.
10.1.1
The individual bits of P1DDR specify input or output for the pins of port 1.
P1DDR cannot be read; if it is, an undefined value will be read.

Description
When a pin function is specified to a general
purpose I/O, setting this bit to 1 makes the
corresponding port 1 pin an output pin, while
clearing this bit to 0 makes the pin an input pin.
