• Manufacturer: RENESAS [Renesas Technology Corp]

This LSI has six I/O ports (ports A, B, D, E, G and H). All port pins are multiplexed with other pin
functions (the pin function controller (PFC) handles the selection of pin functions and pull-up
MOS control). Each port has a data register which stores data for the pins.
23.1
Port A is a 7-bit input/output port with the pin configuration shown in figure 23.1. Each pin has an
input pull-up MOS, which is controlled by the port A control register (PACR) in the PFC.
23.1.1
Port A has the following register. Refer to section 27, List of Registers, for the address of this
register and state of this register in each processing mode.
