Section 20 I/O Ports
This LSI has fourteen I/O ports (ports A to H, J to N, and SC). 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.
20.1 Port A
Port A is an 8-bit input/output port with the pin configuration shown in figure 20.1. Each pin has
an input pull-up MOS, which is controlled by the port A control register (PACR) in the PFC.
