Section 10 I/O Ports
Notes: 1. Not supported by the H8S/2378 0.18μm F-ZTAT Group, H8S/2377, H8S/2375, and
10.1
Port 1 is an 8-bit I/O port that also has other functions. The port 1 has the following registers.
• Port 1 data direction register (P1DDR)
• Port 1 data register (P1DR)
• Port 1 register (PORT1)
10.1.1
The individual bits of P1DDR specify input or output for the pins of port 1.

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.
