5.6.6 Audio Data Packet Error Detection
When the 1-255 count sequence in the Data Block Number (DBN) word of audio data
packets with audio group DID set in DATAIDA[1:0] is discontinuous, the DBNA_ERR bit
3 of Host Interface register 015h will be set HIGH. When the1-255 count sequence in the
DBN word of audio data packets with audio group DID set in DATAIDB[1:0] is
discontinuous, the DBNB_ERR bit 7 of Host Interface register 015h will be set HIGH.
The GS1503B will check the parity (bit 8) for the CLK, CH1-4 and ECC0-5 words in the
embedded audio data packets. When a parity bit error is detected in audio data packets
with audio group DID set in DATAIDA[1:0], the ADPB8A_ERR bit 2 of Host Interface
register 015h will be set HIGH. When a parity bit error is detected in audio data packets
with audio group DID set in DATAIDB[1:0], the ADPB8B_ERR bit 6 of Host Interface
register 015h will be set HIGH.
The GS1503B will re-calculate the audio data packets Checksum and compare against
the embedded Checksum word. When a Checksum error is detected in audio data
packets with audio group DID set in DATAIDA[1:0], the ADPCSA_ERR bit 0 of Host
Interface register 015h will be set HIGH. When a Checksum error is detected in audio
data packets with audio group DID set in DATAIDB[1:0], the ADPCSB_ERR bit 4 of Host
Interface register 015h will be set HIGH.
When any of the above errors are detected, the ERROR external pin will also be set
HIGH.
