Figure 31. Read User Zone Command Functional Description
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 below). The byte address is internally incremented following the
transmission of each data byte. 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.
If the host is not allowed to read the zone, the device will return the "Command Unauthorized" code ($69 $00) after it
has received the header.
