Description
master starts with a START condition
master transmits the device address and read command bit R/W = 1
slave generates an acknowledgment
slave transmits and master reads data from register K. If the start address is
not specified, the read operation starts from where the index register is
pointing to because of a previous read or write operation.
master terminates the read operation by generating a no acknowledgement
master generates a stop condition
Description
master starts with a START condition
master transmits the device address and write command bit R/W = 0
slave generates an acknowledgment
master transmits (start) address of register K from which to be read
slave generates an acknowledgment
master restarts with a START condition
master transmits the device address and read command bit R/W = 1
