D/989/2

ERR

(Bit 2)

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.

(Bits 1 and 0)

Unused, will be set to “0”.
