2.3.6 Update Security Memory (SLE 4442 only)
Regarding the reference data bytes this command will only be executed if a PSC has been
successfully verified before. Otherwise only each bit of the error counter (Address 0) can be written
from “1” to “0”. The execution times and the required clock pulses are the same as described under
UPDATE MAIN MEMORY.
2.3.7 Compare Verification Data (SLE 4442 only)
This command can only be executed in combination with an update procedure of the error counter
(see PSC verification). The command compares one byte of the entered verification data byte with
the corresponding reference data byte. For this procedure clock pulses are necessary during the
processing mode.
