SLEWPD
Codec slew digital clock engine enable. When powered down, the analog playback path volume controls are
disabled and stay set to their current state.
0 = powered down (default).
1 = enabled.
5
ALCPD
ALC digital clock engine enable.
0 = powered down (default).
1 = enabled.
4
DECPD
Decimator resync (dejitter) digital clock engine enable.
0 = powered down (default).
1 = enabled.
3
SOUTPD
Serial routing outputs digital clock engine enable.
0 = powered down (default).
1 = enabled.
2
INTPD
Interpolator resync (dejitter) digital clock engine enable.
0 = powered down (default).
1 = enabled.
1
SINPD
Serial routing inputs digital clock engine enable.
0 = powered down (default).
1 = enabled.
0
SPPD
Serial port digital clock engine enable.
0 = powered down (default).
1 = enabled.
R66: Clock Enable 1, 16,634 (0x40FA)
This register enables Digital Clock Generator 0 and Digital Clock Generator 1. Digital Clock Generator 0 generates sample rates for the
ADCs, DACs, and DSP. Digital Clock Generator 1 generates BCLK and LRCLK for the serial port when the part is in master mode. For
maximum power saving, use this register to disable clocks that are not being used.
