Functional
Figure 14. 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 under Section 7.6.3).
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 Atmel
value of zero will result in 256-bytes read. The host however 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.
If the host is not allowed to read the zone, the device will not acknowledge the N-byte.
