PRESENT_CODE_MEMORY_CARD
To submit the secret code to the memory card to enable the card personalization mode, the following
actions are executed:
1. Search a '1' bit in the presentation counter and write the bit to '0'.
2. Present the specified code to the card.
The ACR3901U-S1 does not try to erase the presentation counter after the code submission. This
must be done by the application software through a separate ‘Write with carry' command.
