This is a general purpose I/O port. When the bits of external address
output control register (HACR) are set to “1” in external bus mode, these
pins function as general purpose I/O ports.
When the bits of external address output control register (HACR) are set
to “0” in multiplex mode, these pins function as address high output pins
(A20 to A23).
When the bits of external address output control register (HACR) are set
to “0” in non-multiplex mode, these pins function as address high output
pins (A20 to A23).
Function as ch0 to ch3 output pins for the 8-bit PPG timer.
General purpose input/output port.
Function as the external address pin in non-multi-bus mode.
Function as an event input pin for 16-bit reload timer ch1.
