Section 9 I/O Ports
Section 9 I/O Ports
The H8S/2268 Group has ten I/O ports (ports 1, 3, 7, F, H, and J to N), and two input-only port
(ports 4 and 9). The H8S/2264 Group has eight I/O ports (ports 1, 3, 7, F, H, and J to L), and two
input-only port (ports 4 and 9).
Table 9.1 summarizes the port functions. The pins of each port also have other functions such as
input/output or interrupt input pins of on-chip peripheral modules.
Each I/O port includes a data direction register (DDR) that controls input/output, a data register
(DR) that stores output data, and a port register (PORT) used to read the pin states. The input-only
ports do not have DDR and DR registers.
Port J has a built-in input pull-up MOS function and an input pull-up MOS control register (PCR)
to control the on/off state of input pull-up MOS.
Port 3 includes an open-drain control register (ODR) that controls the on/off state of the output
buffer PMOS.
All the I/O ports can drive a single TTL load and a 30 pF capacitive load.
The P34 and P35 pins on port 3 are NMOS push pull outputs.
Pins IRQ and WKP are Schmitt-trigger inputs. Pins PH0 to PH3 and ports J to N in the H8S/2268
Group and pins PH0 to PH3 and ports J to L in the H8S/2264 Group are shared as LCD segment
pins and common pins. They can be selected on an 8-bit basis.
