Band Specific Additional Registers The registers in the address space from 0x61 to 0x73 are specific for operation in the lower frequency bands (below 525 MHz), or in the upper frequency bands (above 860 MHz). Their programmed value may differ, and are retained when switching from lower to high frequency and vice-versa. The access to the band specific registers is granted by enabling or disabling the bit 3 LowFrequencyModeOn of the RegOpMode register. By default, the bit LowFrequencyModeOn is at ‘1’ indicating that the registers are configured for the low frequency band.
