Pin Function
PA4/A20/KIN12/CIN12/PS2BC
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 PA4DDR bit.
PA3/A19/KIN11/CIN11/PS2AD
The pin function is switched as shown below according to the combination of operating mode,
the KBIOE bit in KBCRH_0 of the keyboard buffer controller, the IOSE bit in SYSCR, and
the PA3DDR 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, this pin is an NMOS open-drain output, and has direct
open-drain output, and has direct bus drive capability. This pin can always be used as
the PS2BC, KIN12, or CIN12 input pin.
bus drive capability. This pin can always be used as the PS2AD, KIN11, or CIN11 input
pin.
