ADC0 Burst Mode Power-Up Time.
Sets the time delay required for ADC0 to power up from a low power state.
For BURSTEN = 0:
ADC0 power state controlled by AD0EN.
For BURSTEN = 1 and AD0EN = 1:
ADC0 remains enabled and does not enter a low power state after all conver-
sions are complete.
Conversions can begin immediately following the start-of-conversion signal.
For BURSTEN = 1 and AD0EN = 0:
ADC0 enters a low power state (as specified in Table 5.1) after all conversions
are complete.
Conversions can begin a programmed delay after the start-of-conversion sig-
nal.
The ADC0 Burst Mode Power-Up time is programmed according to the follow-
ing equation:
Tstartup
AD0PWR = ---------------------- – 1
400ns
or
Tstartup = AD0PWR + 1400ns
