Read and write anytime.
IIC functions SCL and SDA share port IB pins 7 and 6 and take
precedence over the general-purpose port when IIC is enabled. The
SCL and SDA output buffers behave as open-drain outputs.
When port is configured as input, a read will return the pin level. Port bits
5 through 0 have internal pull ups when configured as inputs so they will
read ones.
When configured as output, a read will return the latched output data.
Port bits 5 through 0 will read the last value written. A write will drive
associated pins only if configured for output and IIC is not enabled.
Port bits 5 through 0 do not have available external pins for
MC68HC912DT128A.
