Datasheet

General SMBus serial interface information for the ICS9LPR501

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 begining 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

• Controllor (host) will send a not acknowledge bit

• Controller (host) will send a stop bit
