Description
master starts with a START condition
master transmits device address and write command bit R/W = 0
slave generates an acknowledgment
master transmits (start) address of register K to be read from
slave generates an acknowledgment
master restarts with a START condition
master transmits device address and read command bit R/W = 1
slave generates an acknowledgment
slave transmits and master reads data from register K. After a byte is read,
the address is automatically incremented by 1.
slave generates an acknowledgment
slave transmits and master reads data from register K + 1

:
register to read. After incrementing, the address rolls over to 0. Here, N
represents the number of addresses available in the slave.
master terminates the read operation by generating a No Acknowledge
master generates a STOP condition
