CLKOUT Pin Source Select
0 = Select CLK1
1 = Select OSCCLK
CLKOUT Pin Disable
0 = Pin Disabled (Pin tri-stated)
1 = Pin Enabled
Fill Mode Select
Determines S/PDIF receiver action when
corrupt or invalid data is detected:
0 = Data from S/PDIF receiver remains static
at last valid sample.
1 = Data from S/PDIF receiver is output as all
zeros.
Always Valid Select
Used to ignore the INVALID flag.
0 = Use INVALID flag.
1 = Ignore INVALID flag.
MCLK Output Source Select
0 = Select CLK2
1 = Select OSCCLK
S/PDIF Input Mode Select
Selects the input circuit type for the receiver
input. The LSB represents RX0 and the MSB
represents RX7
0 = CMOS input
1 = Comparator input. Compatible with
500mVppAC coupled consumer S/PDIF input
signals. Refer to S/PDIF specification (IEC
60958-3) for full details.
Interrupt Mask Enable
When a flag is masked, it does not update the
Error Register or cause an interrupt to be
asserted.
0 = unmask, 1 = mask.
MASK[0] = mask control for UPD_UNLOCK
MASK[1] = mask control for INT_INVALID
MASK[2] = mask control for INT_CSUD
MASK[3] = mask control for INT_TRANS_ERR
MASK[4] = mask control for
UPD_NON_AUDIO
MASK[5] = mask control for UPD_CPY_N
MASK[6] = mask control for UPD_DEEMPH
MASK[7] = mask control for UPD_REC_FREQ
