MUTAD[6:1] ADC Soft Mute control
These bits are used to enable or disable the Soft Mute function for the corresponding ADC
outputs, DOUT. The Soft Mute function is incorporated into the digital attenuators.
When Mute is disabled (MUTAD[6:1] = 0), the attenuator and ADC operate normally. When Mute
is enabled by setting MUTAD[6:1] = 1, the digital attenuator for the corresponding output
decreases from the current setting to infinite attenuation with an s-curve responses and time set
by ATSPAD.
By setting MUTAD[6:1] = 0, the attenuator increases to the last attenuation level with the s-curve
response in same manner as for decreasing levels. This provides pop and zipper noise-free
muting for the ADC input.
The Soft Mute control uses the same digital attenuation level resource setting as the ADC. Mute
control has priority over the digital attenuation level setting.
Default value: 00 0000.
