Initialize the IIC by the procedure shown in figure 16.7 before starting transmission/reception of
data.
Note: Be sure to modify the ICMR register after transmit/receive operation has been completed.

C bus format master transmit mode, the master device outputs the transmit clock and transmit
If the ICMR register is modified during transmit/receive operation, bit counter BC2 to
BC0 will be modified erroneously, thus causing incorrect operation.
