How to Write

• Controller (host) sends a start bit

• Controller (host) sends the write address

• IDT clock will acknowledge

• Controller (host) sends the beginning byte location = N

• IDT clock will acknowledge

• Controller (host) sends the 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 a start bit

• Controller (host) sends the write address

• IDT clock will acknowledge

• Controller (host) sends the beginning byte location = N

• IDT clock will acknowledge

• Controller (host) will send a separate start bit

• Controller (host) sends the read address

• 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
