General SMBus serial interface information for the 9ZX21501C
How to Write:
Controller (host) sends a start bit.
Controller (host) sends the write address XX
(H)
IDT clock will
acknowledge
Controller (host) sends the beginning byte location = N
IDT clock will
acknowledge
Controller (host) sends the data byte count = X
IDT clock will
acknowledge
Controller (host) starts sending
Byte N through
Byte N + X -1
IDT 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 XX
(H)
IDT clock will
acknowledge
Controller (host) sends the begining byte
location = N
IDT clock will
acknowledge
Controller (host) will send a separate start bit.
Controller (host) sends the read addressYY
(H)
IDT clock will
acknowledge
IDT clock will send the data byte count = X
IDT clock sends
Byte N + X -1
IDT 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
