NAME

Audio control packet delay. Designates the audio control packet delay
data as specified in the SMPTE 272M standard. DELA corresponds to
audio channels 1 and 2, while DELB is the corresponds to audio
channels 3 and 4. “DELA/B[25]” is the MSB and “DELA/B[0]” is the
LSB.
Audio control packet synchronization data. Designates the sync mode
bits (asx, asy) as defined in SMPTE 272M (section 14.5) of channels 1/
2 or 3/4 of the audio control packet. The bits are selected by “AC34/
12”.
Audio control packet delay active. Designates the ‘e’ bit of word
“DELx0” of an audio control packet as defined in SMPTE 272 (section
14.7). When HIGH indicates valid audio delay data.
Active channel 1/2 flag.
Active channel 3/4 flag.
Not used.
Audio control packet channel pair select. When set HIGH, audio
control packet delay data for audio channels 3 and 4 is captured in
registers #Ah, #Bh, #Ch and #Dh. When set LOW, audio control packet
delay data for audio channels 1 and 2 is captured in registers Ah, Bh,
Ch and Dh.
AES/EBU channel 1/2 Consumer/Professional status. See AES-3 1992
standard .
AES/EBU channel 1/2 normal/non-audio status. See AES-3 1992
standard .
AES/EBU channel 1/2 emphasis status. “EMPH1/2[2]” is the MSB and
“EMP1/2[0]” is the LSB. See AES-3 1992 standard .
AES/EBU channel 1/2 sync status. See AES-3 1992 standard .
AES/EBU channel 1/2 frequency select status. “FSEL1/2[1]” is the
MSB and “FSEL1/2[0]” is the LSB. See AES-3 1992 standard .
AES/EBU channel 3/4 Consumer/Professional status. See AES-3 1992
standard .
AES/EBU channel 3/4 normal/non-audio status. See AES-3 1992
standard .
AES/EBU channel 3/4 emphasis status. “EMPH3/4[2]” is the MSB and
“EMP3/4[0]” is the LSB. See AES-3 1992 standard .
AES/EBU channel 3/4 sync status. See AES-3 1992 standard .
AES/EBU channel 3/4 frequency select status. “FSEL3/4[1]” is the
MSB and “FSEL3/4[0]” is the LSB. See AES-3 1992 standard .
