ADC0 Low Power Mode Enable.
Enables Low Power Mode Operation.
0: Low Power Mode disabled.
1: Low Power Mode enabled.
Read = 0000b; Write = Don’t Care.
Sets the time delay required for ADC0 to power up from a low power state.
For BURSTEN = 0:
For BURSTEN = 1 and AD0EN = 1:
all conversions are complete.
Conversions can begin immediately following the start-of-conversion signal.
For BURSTEN = 1 and AD0EN = 0:
Conversions can begin a programmed delay after the start-of-conversion signal.
The ADC0 Burst Mode Power-Up time is programmed according to the following
equation:
Note: Setting AD0PWR to 0x04 provides a typical tracking time of 2 us for the first sample
