AFC Rail.
0 = AFC not railed.
1 = AFC railed, indicating an invalid channel. Audio output is softmuted when set.
AFCRL is updated after a tune or seek operation completes and indicates a valid or
invalid channel. During normal operation, AFCRL is updated to reflect changing RF envi-
ronments.
RDS Synchronized (Si4709 only).
0 = RDS decoder not synchronized (default).
1 = RDS decoder synchronized.
Available only in RDS Verbose mode (RDSM 02h[11] = 1).
Refer to “4.4. RDS/RBDS Processor and Functionality”.
RDS Block A Errors (Si4709 only).
00 = 0 errors requiring correction.
01 = 1–2 errors requiring correction.
10 = 3–5 errors requiring correction.
11 = 6+ errors or error in checkword, correction not possible.
Available only in RDS Verbose mode (RDSM 02h[11] = 1).
Refer to “4.4. RDS/RBDS Processor and Functionality”.
Stereo Indicator.
0 = Mono.
1 = Stereo.
RSSI (Received Signal Strength Indicator).
RSSI is measured units of dBµV in 1 dB increments with a maximum of approximately
75 dBµV. Si4708/09-B16 does not report RSSI levels greater than 75 dBuV.
