Response APDU:
Data Field (from card)
SW1 SW2
Data indicates the protection status for the byte located at the corresponding address on the card.
The value ‘00’ indicates the location is protected and cannot be updated. A value ‘01’ indicates
the location is not protected and can be updated.
Possible SW1/SW2 combinations:
SW1/SW2 Meaning
9000
Normal completion, no errors
6B00 Offset outside of the Memory (Combination of P2 and Le is invalid)
Update Binary APDU
Because of card functionality, this APDU should not be sent until at least one Read Binary
APDU has been sent first.
Command APDU:
CLA INS P1 P2 Lc Data
Field
00 D6 Adr1 Adr0 Len Data to be written
CLA is always 00
INS is always D6
P1 is upper byte of address to write and must not be greater than ‘03’
P2 is lower byte of address to write.
Lc is the number of bytes to write, 0-1024
Data Field contains the bytes to write. If a byte to be written is already protected, a status
6581 will be returned.
Response APDU:
SW1 SW2
Possible SW1/SW2 combinations:
SW1/SW2 Meaning
9000
Normal completion, no errors
6581 Memory Failure, some bytes were not written
6B00 Offset outside of the Memory (Combination of P2 and Lc is invalid)
