When the KBIOE bit is set to 1 or the IICS bit in STCR is set to 1, this pin is an NMOS
open-drain output, and has direct bus drive capability. This pin can always be used as
the PS2BD or KIN13 input pin.
When the KBIOE bit is set to 1 or the IICS bit in STCR is set to 1, this pin is an NMOS
open-drain output, and has direct bus drive capability. This pin can always be used as
the PS2BC or KIN12 input pin.
When the KBIOE bit is set to 1, this pin is an NMOS open-drain output, and has direct
bus drive capability. This pin can always be used as the PS2AD or KIN11 input pin.
