e5561
4699A–RFID–04/03
For programming or direct-access mode, the password function has to be disabled by
receiving the password.
If this function is enabled, the customer configuration can only be changed by an autho-
rized person using the correct password of the e5561.
During password mode, the e5561 monitors several fault and protection mechanism. If a
fault or a protection violation is detected, the e5561 enters ID mode.
Error Handling
Several error conditions can be detected to ensure that only valid operations affect the
e5561.
Errors while Writing Data There are four detectable errors possible during writing data to the e5561:
Field gap was not detected
Wrong number of field clocks between two gaps, e.g., 37 FCs
The OPcode is not valid (11)
The number of bits received is incorrect; valid bit counts are:
–
programming mode: 38 bits
–
direct-access mode: 6 bits
–
crypto mode: 66 bits
–
stop mode: 2 bits
If any of these four conditions is detected, the e5561 stops writing and enters ID mode.
This can easily be analyzed using the damping which is usually on during writing. It
changes according to the selected modulation scheme in ID mode.
Errors During Programming
Mode
If the writing sequence has been transmitted successfully, there are three errors that
may prevent the e5561 from programming the data to the EEPROM:
The programming voltage VPP is too low, i.e., the field strength is not high enough
The lock-bit of the adressed block is set
The password function is enabled
In these cases, the procedure stops immediately after the error has been detected and
the IC reverts to ID mode.
Errors During Direct-access
Mode
In addition to the possible errors mentioned before, two errors may occur in direct-
access mode:
The lock-bit of the addressed block 5 to 8 is set
The password function is enabled
In these cases, the IC enters ID mode after the end of the writing sequence.
Errors During Crypto Mode
In crypto mode, ONE error mechanism is active, that may prevent the e5561 from send-
ing the correct response:
Error during the crypto writing sequence
The e5561 will enter ID mode immediately if an error in the writing sequence is detected.
If the password function is enabled, the e5561 enters ID mode after having completed
the writing sequence.
