General SMBus serial interface information for the ICS9LRS4103
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
ICS clock will acknowledge each byte one at a time
Controller (host) sends a Stop bit
How to Read:
Controller (host) will send start bit.
Controller (host) sends the write address D2
(H)
ICS clock will acknowledge
Controller (host) sends the begining 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
ICS clock will send 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
