One chip CD audio device with integrated MP3/WMA decoder
The serial format consists of a pause bit followed by a start bit, followed by data bits. The
format of the data is explained in
Table 10
.
Bit length: seven sysclk periods.
Frame length: 11 bits.
[1]
The CFLG repetition rate is not fixed and depends on disc speed and output interface speed. There is
always at least one pause bit.
[2]
Cormode definition: ‘000’: C1 correction, ‘011’: C2 correction, ‘100’: corrector not active, Others: not used.
[3]
FlagFail and CorFail indicate failure status on previous code word.
[4]
ErrorCount indicates the number of errors found by the error corrector.
6.5.8.2
BLER counters
There are two BLER counters which count the number of frames C1 and C2, with at least
one error. C2 erasures coming from C1 are also counted; it is irrelevant if the frame was
correctable or not.
These registers are reset on read, and the user is responsible for reading them at regular
intervals. The BLER counters can be read by registers C1Bler and C2Bler.
6.5.9
Audio back end and data output interfaces
The channel decoder back end is shown in
