data transferred from the slaves to the I
Follow the steps below for a transmit operation to a 7-bit addressed slave:
1. Software asserts the IEN bit in the I
2. Software asserts the TXI bit of the I
3. The I
4. Software responds to the TDRE bit by writing a 7-bit Slave address plus write bit (=0)
5. Software asserts the START bit of the I
