Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
operating mode, the KBIOE bit in KBCR1H of the keyboard buffer controller,
the IOSE bit in SYSCR, and bit PA4DDR.
When the IICS bit in STCR is set to 1, this pin functions as a bus buffer. This
pin can always be used as the PS2BC, KIN12, or CIN12 input pin.
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 PA3DDR.
This pin can always be used as the PS2AD, KIN11, or CIN11 input pin.
