RDS Ready (Si4709 only).
0 = No RDS group ready (default).
1 = New RDS group ready.
Refer to “4.4. RDS/RBDS Processor and Functionality”.
Seek/Tune Complete.
0 = Not complete (default).
1 = Complete.
The seek/tune complete flag is set when the seek or tune operation completes. Setting
the SEEK 02h[8] or TUNE 03h[15] bit low will clear STC.
Seek Fail/Band Limit.
0 = Seek successful.
1 = Seek failure/Band limit reached.
The SF/BL flag is set high when SKMODE 02h[10] = 0 and the seek operation fails to
find a channel qualified as valid according to the seek parameters.
The SF/BL flag is set high when SKMODE 02h[10] = 1 and the upper or lower band limit
has been reached.
The SEEK 02h[8] bit must be set low to clear SF/BL.
Reserved.
If written, these bits should be read first and then written with their pre-existing values.
Do not write during powerup.
