The figure below demonstrates a typical transaction.
After every 8 bits sent by the
transmitter, the receiver should send one bit low for positive acknowledgement or one bit
high for negative acknowledgement.
After the negative acknowledgement, a STOP or
repeated START should follow. The next figure shows more detailed about
acknowledgement bit. Note that ‘SCLK’ is always driven by the master.

The figure below shows a complete data transfer.
After a START, MCU should send
7-bit slave address (7’b0111000) first, and then the 8th bit denotes a read transfer when
it’s high; or a write transfer when it’s low. The first acknowledgement is always from
CM109.
