Command Set
The command set of Atmel
CryptoMemory exceeds that of a simple memory device. Each instruction sent to the CryptoMemory must have
4-bytes: Command, Address 1, Address 2 and N. The last byte, N, defines the number of any additional data bytes to
be sent or received from the CryptoMemory device. In addition, the Random Read command is available. It is the only
one byte command but must be preceded by an aborted write command in order to set up the read address.
