Refer to “4.4. RDS/RBDS Processor and Functionality”.
Seek Mode.
0 = Wrap at the upper or lower band limit and continue seeking (default).
1 = Stop seeking at the upper or lower band limit.
Seek Direction.
0 = Seek down (default).
1 = Seek up.
Seek.
0 = Disable (default).
1 = Enable.
Notes:
1. Seek begins at the current channel, and goes in the direction specified with the SEEKUP
2. The STC bit is set high when the seek operation completes and/or the SF/BL bit is set
3. Seek performance for 50 kHz channel spacing varies according to RCLK tolerance.
4. A seek operation may be aborted by setting SEEK = 0.

bit. Seek operation stops when a channel is qualified as valid according to the seek
parameters, the entire band has been searched (SKMODE = 0), or the upper or lower
band limit has been reached (SKMODE = 1).
high if the seek operation was unable to find a channel qualified as valid according to the
seek parameters. The STC and SF/BL bits must be set low by setting the SEEK bit low
before the next seek or tune may begin.
Silicon Laboratories recommends ±50 ppm RCLK crystal tolerance for 50 kHz seek
performance.
