6.12.1. Operation

The Read System Zone command reads from the devices configuration memory. The data byte address is internally

incremented as each byte is read from the memory. If the data byte address increments into a segment where read

access is forbidden, the “fuse byte” is transmitted in place of the forbidden data. Only PICCs in the Active State are

permitted to answer this command.

If Authentication or Encryption Communication Security is active the DATA bytes read from the password (PW)

registers are encrypted; no other bytes are encrypted. In the Normal Communication Security mode none of the bytes

are encrypted.
