Table 277. Jewel, (Protocol Number 18)...continued
19.2 CLRC66303 EEPROM configuration
The CLRC66303 user EEPROM had been initalized with useful values for configuration of the chip using a
typical 65x65mm antenna. These values stored in EEPROM can be used to configure the CLRC66303 with the
command LoadReg.Typically, some of this entries will be required to be modified compared to the preset values
to achieve the best RF performance for a specific antenna.
The registers 0x28...0x39 are relevant for configuration of the Antenna. For each supported protocol, a
dedicated preset configuration is available. To ensure compatibility between products of the CLRC663 family,
all products of the family use the same default settings which are initialized in EEPROM, even if some of this
protocols are not supported by the product family member and cannot be used.
Alternatively, the registers can be initialized by individual register write commands.
