Mode 6 [H8S/2351 Only]
In mode 6, port A pins function as address outputs or input ports and interrupt input pins. Input or
output can be specified on an individual bit basis. Setting a PADDR bit to 1 makes the
corresponding port A pin an address output, while clearing the bit to 0 makes the pin an input port.
Port A pin functions in mode 6 are shown in figure 9.10.
