transmitted data is 8 bits, write the transmitted data to SBI0DBR. When the next
transmitted data is other than 8 bits, set the <BC2:0>, set the <ACK> to 1 and
write the transmitted data to SBI0DBR. After written the data, <PIN> becomes 1,
a serial clock pulse is generated for transferring a new 1 word of data from the
SCL pin, and then the one-word data is transmitted. After the data is transmitted,
an INTSBI interrupt request occurs. The <PIN> becomes 0 and the SCL line is
pulled down to the low level. If the data to be transferred is more than one word in
length, repeat the procedure from the <LRB> checking above.

Check the <TRX> and determine whether the mode is a transmitter or receiver.
Check the <LRB>. When <LRB> is 1, a receiver does not request data.
When the <LRB> is 0, the receiver is requests new data. When the next
