Description
Digital Comparator Trigger 5
Value Description
1 Resets the Digital Comparator 5 trigger unit to its initial
conditions.
0 No effect.
When the trigger has been cleared, this bit is automatically cleared.
Because the digital comparators use the current and previous ADC
conversion values to determine when to assert the trigger, it is important
to reset the digital comparator to initial conditions when starting a new
sequence so that stale data is not used.
Digital Comparator Trigger 4
Value Description
1 Resets the Digital Comparator 4 trigger unit to its initial
conditions.
0 No effect.
When the trigger has been cleared, this bit is automatically cleared.
Because the digital comparators use the current and previous ADC
conversion values to determine when to assert the trigger, it is important
to reset the digital comparator to initial conditions when starting a new
sequence so that stale data is not used.
Digital Comparator Trigger 3
Value Description
1 Resets the Digital Comparator 3 trigger unit to its initial
conditions.
0 No effect.
When the trigger has been cleared, this bit is automatically cleared.
Because the digital comparators use the current and previous ADC
conversion values to determine when to assert the trigger, it is important
to reset the digital comparator to initial conditions when starting a new
sequence so that stale data is not used.
Digital Comparator Trigger 2
Value Description
1 Resets the Digital Comparator 2 trigger unit to its initial
conditions.
0 No effect.
When the trigger has been cleared, this bit is automatically cleared.
Because the digital comparators use the current and previous ADC
conversion values to determine when to assert the trigger, it is important
to reset the digital comparator to initial conditions when starting a new
sequence so that stale data is not used.
