Port A
10.7.1
Overview
Port A is a 6-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 change according to the operating mode.
Port A has a built-in MOS input pull-up function that can be controlled by software.
Figure 10-6 shows the port A pin configuration.
