8.2.12.4. PRESENT_CODE_MEMORY_CARD
To submit the secret code to the memory card to enable the card personalization mode, the following
actions are executed:
- Search a '1' bit in the presentation counter and write the bit to '0'
- Present the specified code to the card
The ACR33U-A1 SmartDuo 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.
