Pin Function
PA6/A22/KIN14/CIN14/PS2CC
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 PA6DDR bit.
PA5/A21/KIN13/CIN13/PS2BD
The pin function is switched as shown below according to the combination of operating mode,
the KBIOE bit in KBCRH_1 of the keyboard buffer controller, the IOSE bit in SYSCR, and
the PA5DDR bit.
* When the KBIOE bit is set to 1 or the IICS bit in STCR is set to 1, this pin is an NMOS
* When the KBIOE bit is set to 1 or the IICS bit in STCR is set to 1, this pin is an NMOS
