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.
The first nibble of the command byte corresponds to the device address. All CryptoMemory
devices will 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.
In the following section operations are described in two parts: the instruction is described first
from a functional point of view (parameters and data exchanged), after which they are detailed
for the synchronous two-wire protocol. In these diagrams, values are shown in binary format with
bits to the left transmitted first, i.e. bytes are transmitted most significant bit first.
• Write Commands: ACK polling required except encrypted write commands. Any command
• Set commands: No ACK polling required.
• Verify commands: ACK polling required with B2 or B6 commands only.
