4.1.1 PI (Program Identification)
This RDS data is used to identify broadcasting programs.
After the tuning operation has been completed, the same PI code is input two times or more, so that RDS
data having the same PI code is decoded.
The PI counter is incremented up to eight counts.
If RDS data having different PI codes are input, the PI counter is decremented, and those RDS data are
not decoded, unless they are TP or TA. When the PI counter has been decremented to zero, a differing PI
code is judged to be the correct PI code, the PI counter is incremented, and when the PI counter become
decremented two or more, the RDS data are decoded.
Fig. 4-1 shows the operation of the PI counter.
