interface. The various functions can each be enabled by writing 1 to the corresponding bit of
the port 9 function register (P9FC).
generated. INTKEY interrupt can be used to release all HALT mode.
Port 90 to 97 are 8-bit input ports with pull-up resistors. In addition to functioning as
Resetting resets all bits of the register P9FC to 0 and sets all pins to be input port.
