3.5.14 Demodulator SNR Estimate (Group 3: APR 22 and 23)
3.6 Group 4: Configuration Registers
Read/Write: R
When read, the Demodulator Signal to Noise Ratio (SNR) Estimate
register presents the value for the Demodulator SNR estimate. SNR is
12 bits long. The LSB is found at APR 22, bit 0, and the MSB at
APR 23, bit 3. See
for additional details on SNR[7:0].
Although most Group 4 registers are 8 bits wide, some are as wide as
24 bits. All accesses are done in 8-bit widths. The Address Pointer
Register (APR) is used to access these registers as described in
Section 3.3, “Groups 0 and 1: Address Pointer Register.”
