15:14 BLERB[1:0] RDS Block B Errors.
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 = 1).
Refer to “4.4. RDS/RBDS Processor and Functionality”.
13:12 BLERC[1:0] RDS Block C Errors.
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.

11:10 BLERD[1:0] RDS Block D Errors.
00 = 0 errors requiring correction.
01 = 1–2 errors requiring correction.
10 = 3–5 errors requiring correction.

9:0 READCHAN[9:0] Read Channel.
If BAND 05h[7:6] = 00, then Freq (MHz) = Spacing (MHz) x Channel + 87.5 MHz.
If BAND 05h[7:6] = 01, BAND 05h[7:6] = 10, then
Freq (MHz) = Spacing (MHz) x Channel + 76 MHz.
READCHAN[9:0] provides the current tuned channel and is updated during a seek
operation and after a seek or tune operation completes. Spacing and channel are set
with the bits SPACE 05h[5:4] and CHAN 03h[9:0].
