Mode 6
In mode 6, port A pins function as address outputs or input ports. 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.
Note: Mode 6 cannot be used in the H8S/2240.
Port A pin functions in mode 6 are shown in figure 8.9.
