The first seven bits transmitted in the first byte are
most-significant bits of the 10-bit address. The lowest bit of the first byte transferred is the
read/write control bit (=0). The transmit operation is carried out in the same manner as 7-
bit addressing.
Follow the steps below for a transmit operation on a 10-bit addressed slave:
1. Software asserts the IEN bit in the I
2. Software asserts the TXI bit of the I
3. The I
