Additional Notes
In addition to the above processing, processing required for layer 3 (data group) level processing includes “deletion of
inappropriate data.” Although rare, in certain cases the IC will send inappropriate packet data that does not belong to any
data group currently being broadcast. The following three points are possible reasons for this occurring.
(1) The IC frame synchronization circuit generates an incorrect synchronization state, and the IC incorrectly outputs
parity packet data as normal packet data. This can occur when the back protection count is less rigorous (2 or lower),
or during weak field reception.
(2) While extremely rare, incorrect correction can occur. (This almost never happens.)
(3) Noise entering the data transfer lines between the FMD IC and the CPU within the end product set.
Inappropriate packet data that occurs for these reasons and does not belong to any data group, will not be updated, and
will remain in the program storage memory indefinitely. If the application does not include a routine that searches for and
deletes inappropriate data, program storage memory will overflow at some point.
Also, applications should perform a layer 4 CRC check after data group completion and before program display.
