Port 9 (P90 to P97)
general-purpose I/O port, port 90 to 97 can also key-on wakeup function as keyboard
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 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.
And resetting resets all bits of the register P9UE to 1 and sets all pins to be pull-up port.
When P9FC = 1, if either of input of KI0 to KI7 pins falls down, INTKEY interrupt is
