General SMBus serial interface information for the 9FGP204
How to Write:
• Controller (host) sends a start bit.
• Controller (host) sends the write address D0
(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 D0
(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 D1
(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
