WRITE byte
The WRITE byte protocol is used to write one byte of data to the registers as shown in
Table
SMBus WRITE byte protocol
READ byte
The READ byte protocol is used to read one byte of data from the registers as shown in
Table
SMBus READ byte protocol
SEND byte
The SEND byte protocol is used to set the internal address register to the correct address. It
sends a register address with no data (see
RECEIVE byte protocol described below in order to read data from the register.

RECEIVE byte
The RECEIVE byte protocol is used to read data from the register when the internal register
address pointer is known (see
