2.12.12.2 Channel-Specific Configuration
This section contains the channel-specific part of a service configuration.
FFREQ[2:0]
The FFREQ[2:0] variables are a copy of the fractional frequency registers (FFREQ[2:1]L/M/H) and contain the base frequency setting for the fractional-N PLL. See Demodulation Settings for a functional description, and Fractional-N PLL for a hardware description.

FEMS
The FEMS variable is a copy of the RF front end main and swallow control register (FEMS) and contains the main and swallow counter values of the fractional-N PLL. See Demodulation Settings for a functional description, and Fractional-N PLL for a hardware description.

Bits 7..6: Reserved Bits
These bits are reserved for future use and must be set to ‘0
’.
Bit 5: ANPS – ASK not DPSK Switch.
This bit must be set to ‘0
’ because the function is controlled by the
firmware/SSM.
Bit 4: PLCKG – PLL Lock Detect Gate
This bit must be set to ‘0
’ because the function is controlled by the
firmware/SSM.
Bit 3: ADHS – ADC High Sample Rate
This bit must be set to ‘0
’ because the function is controlled by the
firmware/SSM.
Bit 2: ANDP – Antenna Damping
This bit must be set to ‘0
’ because the function is controlled by the
firmware/SSM.
Bit 1: S4N3 – Select 433 MHz not 315 MHz Band
Bit 0: LBNHB – Select Low-Band not High-Band
