AES auth key for Master Card and Config push
02F4 (bank 2, register
Size : 16 bytes
Type : array (fixed length)
Master Cards are protected by a key-set, combining AES keys to read the Master Card, and an ECC key-pair to prove the authenticity of its content. This register stores the AES key that protects the data on the card. The same AES key is used for Config push.
