Description
Reserved for factory use.
Direct control of the PA_ON pin.
When cleared to 0 the PA_ON pin is in the OFF state (PAVDD).
When set to 1 the PA_ON pin is in the ON state (AGND).
When read, the value of this bit reflects the state of the PA_ON
pin.
This register uses software to force the corresponding DAC into
clamp.
If 1, the corresponding DAC or DAC pair is forced into
clamp.
If 0, the corresponding DAC or DAC pair is restored to
normal operation.
If a DAC or DAC pair is in clamp mode through a SLEEP pin the
corresponding clamp bit is automatically set to 1.
