The PI code same as the PI code stored in block 4 of the data sent by 14A is searched from the pool
memory.
If the PI code that coincides with the PI code stored in block 4 is found, the next frequency of block
3 of the data sent by 14A is registered in the AF list attached to that PI code.
G
AF list sent by Usage Code 4
G
Mapped FM frequency sent by Usage Code 5-8
2
Remark
The frequency is registered in 2 as follows:
G
Registering an AF list sent by Usage Code 4
Up to eight stations are input to a work area.
If the PI code sent by block 4 of 14A is changed, or if the receive frequency is changed,
the data in the work area is updated to accept the AF list of the PI code that coincides.
If a PI code that coincides is not found, the work area is updated to be a new pool memory.
If there is no vacant pool memory, pool memories are overwritten starting from the oldest
one that is not registered to preset memory.
G
Registering an AF list sent by Usage Codes 5 to 8
(a) If a PI code that coincides already exists in pool memory
The AF list in the pool memory is directly updated (refer to the figure below).
The storage positions corresponding to Usage Codes 5 to 8 are predetermined as
shown in the above figure. AF1 takes the highest priority for AF selection.
In this case, even if the AF list in a pool memory has been already registered, the pool
memory is overwritten when Usage Codes 5 to 8 are input.
(b) If the PI code that coincides is not in pool memory
In this case, the same assumption is made as when a PI code that coincides is missing
in the case of Usage Code 4.
For traffic information interrupt operation of a station other than the received station, refer to 4.1.6 TP,
TA.
4.1.6 TP (Traffic Program Identification), TA (Traffic Announcement Identification)
These data are used to identify a traffic information station or traffic information announcement.
A traffic information station is identified as follows:
When TP = 1
When TP = 0 and TA = 1
