How to Write:
• Controller (host) sends a start bit.
• Controller (host) sends the write address DC
• ICS clock will acknowledge
• Controller (host) sends the begining byte location = N
• ICS clock will acknowledge

How to Read:
• Controller (host) will send start bit.
• Controller (host) sends the write address DC
• ICS clock will acknowledge
• Controller (host) sends the begining byte
• ICS clock will acknowledge
• Controller (host) will send a separate start bit.
• Controller (host) sends the read address DD
• 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
• Controller (host) will need to acknowledge each byte
• Controllor (host) will send a not acknowledge bit
• Controller (host) will send a stop bit
