9.8.3 Pin Functions
Mode 1 [H8S/2350]; Modes 1, 2, 3 and 7 [H8S/2351]: In mode 1, 2, 3, and 7*, port A pins
function as I/O ports and interrupt input pins. 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 in modes 1, 2, 3, and 7* are shown in figure 9-8.
Note: * Modes 2, 3, and 7 only apply to the H8S/2351.
