CODE: N bytes of Erase Key
Response data format (abData field in the RDR_to_PC_DataBlock)
SW1 SW2
Where:
SW1, SW2 = 90 00h if no error
Note: After SW1SW2 = 0x9000h has been received, read back the data in Application Zone can
check whether the ERASE_APPLICATION_ZONE_WITH_ERASE is correct. If all data in
Application Zone is erased and equals to “0xFFh”, the previous verification is success.

• AT88SC101: To erase the data in Application Zone with EC Function Enabled
• AT88SC102: To erase the data in Application Zone 2 with EC2 Function Enabled
• AT88SC1003: To erase the data in Application Zone 2 with EC2 Function Enabled
With EC or EC2 Function Enabled (that is, ECEN or EC2EN Fuse is undamaged and in “1” state), the
following actions are executed:
• Present the specified code to the card
• Search a '1' bit in the presentation error counter and write the bit to '0'
• Erase the presentation error counter. The data in corresponding Application Zone can be
erased when the submitted code is correct.
