Pin Function
PA7/A23/KIN15/CIN15/PS2CD
The pin function is switched as shown below according to the combination of operating mode,
the KBIOE bit in KBCRH_2 of the keyboard buffer controller, the IOSE bit in SYSCR, and
the PA7DDR bit.
* The initial value is determined according to the PA7 to PA0 pin states.
* When the KBIOE bit is set to 1 or the IICS bit in STCR is set to 1, this pin is an NMOS
