How to Write:
• Controller (host) sends a start bit.
• Controller (host) sends the write address D4
• ICS clock will acknowledge
• Controller (host) sends a dummy command code
• ICS clock will acknowledge
• Controller (host) sends a dummy byte count
• ICS clock will acknowledge
• Controller (host) starts sending first byte (Byte 0)
• ICS clock will acknowledge each byte one at a time.
• Controller (host) sends a Stop bit

The ICS clock generator is a slave/receiver, I
for verification. Read-Back will support Intel PIIX4 "Block-Read" protocol.
The data transfer rate supported by this clock generator is 100K bits/sec or less (standard mode)
The input is operating at 3.3V logic levels.
The data byte format is 8 bit bytes.
To simplify the clock generator I
The bytes must be accessed in sequential order from lowest to highest byte with the ability to stop after any
complete byte has been transferred. The Command code and Byte count shown above must be sent, but the
data is ignored for those two bytes. The data is loaded until a Stop sequence is issued.
At power-on, all registers are set to a default condition, as shown.

How to Read:
• Controller (host) will send start bit.
• Controller (host) sends the read address D5
• ICS clock will acknowledge
• ICS clock will send the byte count
• Controller (host) acknowledges
• ICS clock sends first byte (Byte 0) through byte 6
• Controller (host) will need to acknowledge each byte
• Controller (host) will send a stop bit
