Fuses
FAB, CMA, and PER are nonvolatile fuses blown at the end of each card life step. Once
blown, these EEPROM fuses can not be reset.
The FAB fuse is blown by Atmel prior to shipping wafers to the card manufacturer.
The CMA fuse is blown by the card manufacturer prior to shipping cards to the
issuer.
The PER fuse is blown by the issuer prior to shipping cards to the end user.
The fuses are read and written in the configuration zone using the address $80.
