Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
operating mode, the KBIOE bit in KBCR0H of the keyboard buffer controller,
the IOSE bit in SYSCR, and bit PA2DDR.
This pin can always be used as the PS2AC, KIN10, or CIN10 input pin.
The pin function is switched as shown below according to the combination of
operating mode, the IOSE bit in SYSCR, and bit PA1DDR.
This pin can always be used as the KIN9 or CIN9 input pin.
The pin function is switched as shown below according to the combination of
operating mode, the IOSE bit in SYSCR, and bit PA0DDR.
This pin can always be used as the KIN8 or CIN8 input pin.
