Section 8 I/O Ports
8.1
Overview
The H8S/2138 Group and H8S/2134 Group have eight I/O ports (ports 1 to 6, 8, and 9), and one
input-only port (port 7).
Tables 8.1 and 8.2 summarize 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) and data registers (DR, ODR) that store output data.
Ports 1 to 3, and 6 have an on-chip MOS input pull-up function. Ports 1 to 3 and 6 have a MOS
input pull-up control register (PCR), in addition to DDR and DR, to control the on/off status of the
MOS input pull-ups.
Ports 1 to 6, 8, and 9 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, 2, and 3 can drive an LED (10 mA
sink current).
In the H8S/2138 Group, P52 in port 5 and P97 in port 9 are NMOS push-pull outputs.
Note that the H8S/2134 Group has subset specifications that do not include some supporting
modules. For differences in pin functions, see table 8.1, H8S/2138 Group Port Functions, and table
8.2, H8S/2134 Group Port Functions.
