Section 9 I/O Ports
9.6
9.6.1
Port A is a 4-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 an on-chip MOS input pull-up function that can be controlled by software.
Figure 9-5 shows the port A pin configuration.
