SIO Clock
This is the input/output pin for the clock signal used for
SIO serial data transfer.
In external clock mode, the clock signal for serial data
transfer is input at this pin.
In internal clock mode, the clock signal from the
internal clock generator is output at this pin.
This pin has internal pull-up resistance (MB86941
only).
SIO Receive Data input pin
This pin receives data input LSB first, synchronously
with the SICLK pin clock signal. This pin has internal
pull-up resistance (MB86941 only).
SIO Transmit Data output pin
This pin outputs data LSB first, synchronously with the
SICLK pin clock signal.
