To read data on the I
in this sequence:
1. Write slave device address to Device Address register (DAR). The data contains 7 bits device
2. Write control data to Control and Status register. Write a 1 to bit 1 to start I
3. Wait for I
4. Read data from the Read Data register (RDR).
5. Read data from Secondary Read Data register (SRDR) if bit 0 of Control and Status register (CSR) is
