Acknowledge Polling
Each command is ended with a stop condition. Certain commands are required to be followed by an acknowledge
polling sequence. Acknowledge polling consists of sending a start condition followed by the command byte and
determining if the device responded with an ACK. If the device is not ready for the command it will not acknowledge
and the sequence must be repeated (start condition, command byte, check for ACK). The ACK indicates the operation
has completed but gives no indication of the success or failure of the command.

The following table lists the specific requirements for ACK polling and the maximum expected delay before the device
will ACK indicating readiness for the next command.
Delays are based on operation at 25° C.
Device Addressing
The first nibble of the command byte corresponds to the device address. All Atmel
respond to the device address $B. A specific device may be set to respond to another value ($0 to $F) in addition to $B
by setting this value in the second nibble of the Device Configuration Register (DCR) in the configuration memory. The
DCR is set to $FF at the Atmel factory and thus will respond to device address $B and $F unless the DCR is modified.
For a device to respond only to $B the DCR should be set to $B also.
