CMX989
ERR
(Bit 2)
(Bits 1 and 0)
This bit indicates whether the data currently being read out from RX DATA BUFFER
has any errors. If this bit is set to “1” there are errors that cannot be corrected and
the host µController should discard all data in the present frame as that frame
cannot be successfully completed. It will then search and re-synchronise to the next
frame flag, before making any more data available. When this bit is set to “0” there
are no errors in the block currently being read.
Note: Due to the CMX989's internal buffer, the data currently being read at the
CMX989/µController interface may be up to 5 Reed-Solomon blocks older than
the data currently being received at the CMX989/FM demodulator interface.
Unused, will be set to “0”.
