Modes 4 to 6: In modes 4 to 6, port A pins function as address outputs according to the setting of
AE3 to AE0 in PFCR; when they do not function as address outputs, the pins function as SCI I/O
pins and I/O ports.
Port A pin functions in modes 4 to 6 are shown in figure 9-6.
Mode 7: In mode 7, port A pins function as I/O ports and SCI2 I/O pins (SCK2, TxD2, RxD2).
Input or output can be specified for each pin on an individual bit basis. Setting a PADDR bit to 1
makes the corresponding port A pin an output port, while clearing the bit to 0 makes the pin an
input port.
Port A pin functions are shown in figure 9-7.
