Fill Mode Overwrite Configuration
Determines S/PDIF receiver action when TRANS_ERR or
INVALID flag is masked and error condition sets the flag:
0000 = INT_N
0001 = V
0010 = U
0011 = C
0100 = P
0101 = SFRM_CLK
0110 = 192BLK
0111 = UNLOCK
1000 = CSUD
1001 = Invalid
1010 = ZFLAG
1011 = NON_AUDIO
1100 = CPY_N
1101 = DEEMP
1110 = Set GPO as S/PDIF input (standard CMOS input buffer).
Only applicable for GPO3/4/5.
1111 = Set GPO as S/PDIF input (‘comparator’ input for AC
coupled consumer S/PDIF signals). Only applicable for GPO3/4/5
Automatic Error Handling Configuration for INVALID Flag
0000 = INT_N
0001 = V
0010 = U
0011 = C
0100 = P
0101 = SFRM_CLK
0110 = 192BLK
0111 = UNLOCK
1000 = CSUD
1001 = Invalid
1010 = ZFLAG
1011 = NON_AUDIO
1100 = CPY_N
1101 = DEEMP
1110 = Set GPO as S/PDIF input (standard CMOS input buffer).
Only applicable for GPO3/4/5.
1111 = Set GPO as S/PDIF input (‘comparator’ input for AC
coupled consumer S/PDIF signals). Only applicable for GPO3/4/5
UNLOCK flag update signal
INVALID flag interrupt signal
0 = INVALID flag automatic error handling enabled.
1 = INVALID flag automatic error handling disabled.
0 = Data from S/PDIF receiver is overwritten with last valid
data sample when flag is set.
1 = Data from S/PDIF receiver is overwritten as all zeros
when flag is set.
0 = INT_N not caused by update to UNLOCK flag
1 = INT_N caused by update to UNLOCK flag
0 = INT_N not caused by INVALID flag
1 = INT_N caused by INVALID flag
