8.10.3
PORTA shows the pin states of the port A. PORTA cannot be modified.
Notes: 1. Determined by the state of the HUDIDI/RxD0 pin.
8.10.4
Port A pins also function as the pins for external address bus output, external bus control signal
output, and interrupt input. The correspondence between the register specification and the pin
functions is shown below.

Pin function
The pin function is switched as shown below according to the combination of the PA3DDR
bit, the EXPE bit in MDCR, and the CS3E and AHOE bits in PFCR1.

Description
This bit is read as the reversed value of the
HUDIDI/RxD0 pin. 1 is read when the HUDIDI/RxD0 pin
is low, and 0 is read when HUDIDI/RxD0 pin is high.
Reserved
If these bits are read, an undefined value will be read.
If a PORTA read is performed while PADDR bits are set
to 1, the PADR values are read. If a PORTA read is
performed while PADDR bits are cleared to 0, the pin
states are read.
