Pin Function
P97/WAIT/SDA0
The pin function is switched as shown below according to the combination of operating mode,
the WMS1 bit in WSCR, the ICE bit in ICCR of IIC_0, and the P97DDR bit.
NMOS open-drain output, and has direct bus drive capability.
* The initial value of bit 6 is determined according to the P96 pin state.

Description
With the exception of P96, if a port 9 read is
performed while P9DDR bits are set to 1, the
P9DR values are read directly, regardless of the
actual pin states. If a port 9 read is performed
while P9DDR bits are cleared to 0, the pin states
are read.
For P96, the pin state is always read.
