High performance ISO/IEC 14443 A/B reader solution
8.7.3 EEPROM initialization content LoadProtocol
The MFRC631 EEPROM is initialized at production with values which are used to reset
certain registers of the MFRC631 to default settings by copying the EEprom content to
the registers. Only registers or bits with “read/write” or “dynamic” access rights are
initialized with this default values copied from the EEProm.
Note that the addresses used for copying reset values from EEprom to registers are
dependent on the configured protocol and can be changed by the user.
The register reset values are configuration parameters used after startup of the IC. They
can be changed to modify the default behavior of the device. In addition to this register
reset values, is the possibility to load settings for various user implemented protocols.The
load protocol command is used for this purpose.
