INTERR:
INTPCM:
ERROR signal output setting
0: Do not output this signal. (initial value)
1: Output the change in the ERROR pin state.
______________
AUDIO signal output setting
0: Do not output this signal._{__}(_{_}i_{_}n_{__}i_{_}t_{_}i_{__}a_{_}l_{__}v_{_} alue)
1: Output the change in the AUDIO pin state.
INTEMP:
Setting of emphasis detection flag output of channel status
0: Do not output this flag. (initial value)
1: Output the emphasis detection flag.
INTVFL:
Setting of validity flag detection flag output
0: Do not output this flag. (initial value)
1: Output the validity flag.
INTFSC:
Setting of updated flag output of PLL lock frequency calculation result
0: Do not output this flag. (initial value)
1: Output updated flag for the PLL lock frequency calculation result.
INTCSF:
Setting of updated flag output of the first 48 bits channel status data
0: Do not output this flag. (initial value)
1: Output the updated flag for the first 48 bits of channel status data.
INTQSY:
Setting of signal detection flag output of Sub-code Q data readout load
0: Do not output this flag. (initial value)
1: Output the updated flag for the 80 bits of sub-code Q data including the CRC.
• Use INTFSC, the updated flag, of PLL lock frequency calculation result together with INTERR that output the change
in the ERROR state. INTFSC is compared with the target fs of the input fs calculation result. When an fs change
other than the target fs is found and the fs change doesn’t contain a PLL lock error, INTFSC is valid and the updated
flag is output. However, if the fs change contains a PLL lock error, then INTFSC is not valid as a lock error process
occurs first and the updated flag is not output.
• The channel status updated flag is computed by comparing the current data with the first 48 bits of the previous block.
If those data are identical, the channel status is updated and the flag is output.
