Temperature monitor for microprocessor systems
8.6 SMBus interface
The device can communicate over a standard 2-wire serial interface System Management
Bus (SMBus) using the device pins SCLK and SDATA. The device employs four standard
SMBus protocols: write byte, read byte, send byte and receive byte. Data formats of those
protocols are shown in Figure 3
with following notifications:
" The SMBus master initiates data transfer by establishing a START condition (S) and
terminates data transfer by generating a STOP condition (P).
" Data is sent over the serial bus in sequence of 9 clock pulses according to each 8-bit
data byte followed by 1-bit status of the device acknowledgement.
" The 7-bit slave address is equivalent to the selected address of the device.
" The command byte is equivalent to the selected command of the device register.
" The send byte format is often used for the one-shot conversion command.
" The receive byte format is used for quicker transfer data from a device reading
register that was previously selected by a read byte format.
a. Write byte format (for writing data byte to the device register)
b. Read byte format (for reading data byte from the device register)
c. Send byte format (for sending command without data, such as one-shot command)
d. Receive byte format (for continuously reading from device register)
