Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
operating mode, the KBIOE bit in KBCR2H of the keyboard buffer controller,
the IOSE bit in SYSCR, and bit PA6DDR.
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 PS2CC, KIN14, or CIN14 input pin.
