This section describes data transmit control when a master transferes data or a slave receives data in 7-bit
address format. Figure 16.20 (1) shows a master transmit format.

6) Set “E0
7) Set the destination address in 7 high-order bits and "0" to a least significant bit in the S00 register
8) Set a transmit data to the S00 register. At this time, SCL and an ACK clock are automatically
