7.6.2.1 Functional
The Read User Zone command $B2 allows reading of data from the device's currently selected user zone (the procedure for selecting a user zone is described in section 7.6.3 System WRITE: $B4.
The data byte address to be read is defined by Address 1 and Address 2 in the command and is internally incremented following the transmission of each data byte. The value N defines how many bytes CryptoMemory® will read; a value of zero will result in 256 bytes read. The host may cease clocking the device and end the transmission with a NACK and stop at any time prior to receiving all N bytes. During a read operation, the address will roll over from the last byte of the current zone to the first byte of the same zone.
