Description
Reserved for factory use
Setting this bit to 1 imposes an additional write to the PA_ON
register to set the PA_ON pin to the ON state after clearing the
SLEEP2 pin.
Setting this bit to 0 enables the SLEEP2 pin to set the PA_ON
pin to the ON state directly.
Setting any of these bits to 1 imposes an additional write to the
CLAMP Configuration register to wake-up the corresponding
DAC or DAC pair from clamp after clearing the SLEEP2 pin.
Clearing any of these bits to 0 enables the SLEEP2 pin to wake-
up the DAC or DAC pairs directly.
Reserved for factory use
Setting this bit to 1 allows control of the PA_ON pin through the
SLEEP2 pin. When SLEEP2 pin goes high the PA_ON pin
enters the OFF state.
Bringing the SLEEP2 pin low is required but not necessarily
sufficient to return the PA_ON pin to the ON state as determined
by the SNOOZE bits.
Setting this bit to 0 causes the PA_ON pin to be unaffected by
the SLEEP2 pin.
Setting any of these bits to 1 allows control of the corresponding
DAC or DAC pair through the SLEEP2 pin. When SLEEP2 pin
goes high the DAC or DAC pair goes into clamp mode.
Bringing the SLEEP2 pin low is required but not necessarily
sufficient to return the DAC or DAC pairs to normal operation as
determined by the SNOOZE bits.
Clearing any of these bits to 0 causes the corresponding DAC or
DAC pair to be unaffected by the SLEEP2 pin.
