Product data sheet
7.21 RDS update or alternative frequency jump
A channel which transmits RDS data can have alternative channels which carry the same
information. These alternative channel frequencies are in the RDS data, so the host
processor can read the alternative frequencies and store them in a memory. More details
on this subject can be found in section 3.5 of RDS: The Radio Data System, Dietmar
Kopitz and Bev Marks .
