Overview
The H8S/2345 Group has 10 I/O ports (ports 1, 2, 3, and A to G), and one input-only port (port 4).
Table 8.1 summarizes the port functions. The pins of each port also have other functions.
Each port includes a data direction register (DDR) that controls input/output (not provided for the
input-only port), a data register (DR) that stores output data, and a port register (PORT) used to
read the pin states.
Ports A to E have a built-in MOS input pull-up function, and in addition to DR and DDR, have a
MOS input pull-up control register (PCR) to control the on/off state of MOS input pull-up.
Ports 3 and A include an open-drain control register (ODR) that controls the on/off state of the
output buffer PMOS.
Ports 1, and A to F can drive a single TTL load and 90 pF capacitive load, and ports 2, 3, and G
can drive a single TTL load and 30 pF capacitive load. All the I/O ports can drive a Darlington
transistor when in output mode. Ports 1, and A to C can drive an LED (10 mA sink current).
Port 2, and interrupt input pins (IRQ0 to IRQ7) are Schmitt-triggered inputs.
For block diagrams of the ports see appendix C, I/O Port Block Diagrams.
