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