Description
master starts with a START condition
master transmits device address and write command bit R/W = 0
slave generates an acknowledgment
master transmits address of register K. This is the start address for writing
multiple data bytes to consecutive registers. After a byte is written, the
register address is automatically incremented by 1.
Remark: If the master writes to a non existent register, the slave must send
a 'not ACK' and also must not increment the index address.
