1.2.1.9 FB ADC Rate configuration
This macro specifies the Analog-to-Digital Converter (ADC) sampling rate(s) for the FB channel(s). The
supported rates are tabulated below. In case the ADC used for an FB channel is the same as that for a
particular RX channel, the ADC rate configured for both should be identical.
