Erase Binary APDU

The Erase Binary command is used to erase specific bytes in the card. For this type of card
erased means that each bit = 1.

If the bytes specified by Adr and Cnt is in the range specified by the Counter Lowest Address
and the Counter Highest Address properties, the command will not be processed. Warning: the
GAM375 address can “wrap” around. If you specify Adr = 0x28 and Cnt = 0x28 you will
wrap around to the start of the card and end up erasing the counter bytes! There are many
possible combinations of Adr and Cnt that could result in a wrap around erasing the counter
bytes, so be careful.

This command erases each byte starting at the specified address for as many bytes as specified
by Cnt.

Command APDU:

CLA

INS

Data

Cnt

Adr

CLA is always D0

INS is always 0A

P1 gives Cnt, which is the count of bytes to be erased
P2 gives Adr, which is the address where the erase will occur

Lc must be 00
Data is empty
