Error report
The validity of bit allocation plus scale factor select information and the result of the scale factor CRCs (only when scale
factor CRCs are enabled) may be read from the error report register. The error report is only valid when status flag
INSYNC is set.
Table 50
Error report register: 1 byte (read-only, restricted type, local address = 24H)

DESCRIPTION
BALOK
bit allocation and scale factor select information validity indication:
logic 0; bit allocation or scale factor select information are incorrect or the CRC over
header plus bit allocation plus scale factor select information has failed
logic 1; bit allocation and scale factor select information are correct and CRC over
header plus bit allocation plus scale factor select information is correct or not active
frame skipping or frame decoding indication:
logic 0; current input data frame is skipped, and the corresponding baseband audio
output frame is muted due to input data errors or inconsistencies; audio frame
synchronization is maintained
logic 1; current frame is decoded normally
scale factor CRCs not enabled; bits are invalid
scale factor CRCs enabled:
logic 0; one or more scale factors have been concealed in sub-band block 0 to 3
logic 1; no scale factor concealment in sub-band block 0 to 3 (CRC check was OK)
block 0; sub-bands 0 to 3
block 1; sub-bands 4 to 7
block 2; sub-bands 8 to 15
block 3; sub-bands 16 to 31
