Port A

9.7.1

Overview

Port A is an 8-bit I/O port. Port A pins also function as address bus outputs and SCI2 I/O pins

(SCK2, RxD2, and TxD2). The pin functions depend on the operating mode.

Port A has an on-chip MOS input pull-up function that can be controlled by software.

Figure 9.6 shows the port A pin configuration.
