I
byte of data after a write frame to the correct slave address is interpreted as the register address; this address auto-increments after each byte written or read.
The frame formats are shown below.

The first byte transmitted by the Master is the Slave Address followed by the R/W bit.
The Slave acknowledges by sending a "1" bit.
