‘0’ enables the SPDIF_OUT pin (note that GC5 in register 4Ch
must also be set to 0, and SEN in register 2Ah to 1)
‘0’ enables the ADCIRQ pin (note that GC4 in register 4Ch must
also be set to 0).
‘0’ enables the PENDOWN pin (note that GC3 in register 4Ch
must also be set to 0).
‘0’ enables the GENIRQ pin (note that bit GC2 in register 4Ch
must also be set to 0).
Read-only bit to indicate DAC auto-muting
