Voice ADC status. A 1-bit value to indicate the hard mute status of the
voice ADC. If bit VS = 1, then power-down is ready and the clock may be
disabled; if bit VS = 0, then power-down is not ready and the clock should
not be disabled.
ADC 2 status. A 1-bit value to indicate the hard mute status of ADC 2. If
bit AS1 = 1, then power-down is ready and the clock may be disabled; if
bit AS1 = 0, then power-down is not ready and the clock should not be
disabled.
ADC 1 status. A 1-bit value to indicate the hard mute status of ADC 1. If
bit AS0 = 1, then power-down is ready and the clock may be disabled; if
bit AS0 = 0, then power-down is not ready and the clock should not be
disabled.
DAC channel 5 and channel 6 status. A 1-bit value to indicate the hard
mute status of DAC channel 5 and channel 6. If bit DS2 = 1, then
power-down is ready and the clock may be disabled; if bit DS2 = 0, then
power-down is not ready and the clock should not be disabled.
DAC channel 3 and channel 4 status. A 1-bit value to indicate the hard
mute status of DAC channel 3 and channel 4. If bit DS1= 1, then
power-down is ready and the clock may be disabled; if bit DS1 = 0, then
power-down is not ready and the clock should not be disabled.
DAC channel 1 and channel 2 status. A 1-bit value to indicate the hard
mute status of DAC channel 1 and channel 2. If bit DS0 = 1, then
