SW1 SW2
Where:
SW1 SW2
= 90 00h if no error
Note:
After SW1SW2 = 0x9000h has been received, read back the data in Application Zone to
check if the ERASE_APPLICATION_ZONE_WITH_ERASE is correct. If all data in Application
Zone is erased and is equal to “0xFFh,” the previous verification is successful.
8.3.9.6. ERASE_APPLICATION_ZONE_WITH_WRITE_AND_ERASE
This command can be used in the following cases:
1. AT88SC101: To erase the data in Application Zone with EC Function Enabled.
2. AT88SC102: To erase the data in Application Zone 2 with EC2 Function Enabled.
3. 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:
1. Present the specified code to the card.
2. Search a '1' bit in the presentation error counter and write the bit to '0'.
3. Erase the presentation error counter. The data in corresponding Application Zone can be
