General SMBus Serial Interface
How to Write:
Controller (host) sends a start bit
Controller (host) sends the write address D2
(H)
ICS clock will acknowledge
Controller (host) sends the beginning byte location =N
ICS clock will acknowledge
Controller (host) sends the data byte count = X
ICS clock will acknowledge
Controller (host) starts sending Byte N through Byte N + X
- 1 (see Note 2)
ICS clock will acknowledge each byte one at a time
Controller (host) sends a Stop bit
How to Read:
Controller (host) sends a start bit
Controller (host) sends the write address D2
(H)
ICS clock will acknowledge
Controller (host) sends the beginning byte location =N
ICS clock will acknowledge
Controller (host) will send a separate start bit
Controller (host) sends the read address D3
(H)
ICS clock will acknowledge
Controller (host) sends the data byte count = X
ICS clock sends Byte N + X - 1
ICS clock sends Byte 0 through byte X (if X
(H) was written
to byte 8)
Controller (host) will need to acknowledge each byte
Controller (host) will send a not acknowledge bit
Controller (host) will send a stop bit
