functioning as general-purpose I/O ports, ports A0 to A7 can also, as a Keyboard interface,
operate a Key-on wake-up function. The various functions can each be enabled by writing a
“1” to the corresponding bit of the Port A Function Register (PAFC).
Resetting resets all bits of the register PAFC to “0” and sets all pins to be input port.
generated. An INTKEY interrupt can be used to release all HALT modes.
Port A (PA0 to PA7)
Ports A0 to A7 are 8-bit general-purpose input ports with pull-up resistor. In addition to
When PAFC = “1”, if the input of any of KI0-KI7 pins falls down, an INTKEY interrupt is
