Description
Digital Comparator Trigger 1
Value Description
1 Resets the Digital Comparator 1 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 0
Value Description
1 Resets the Digital Comparator 0 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.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Digital Comparator Interrupt 7
Value Description
1 Resets the Digital Comparator 7 interrupt unit to its initial
conditions.
0 No effect.
When the interrupt 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 interrupt, 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 Interrupt 6
Value Description
1 Resets the Digital Comparator 6 interrupt unit to its initial
conditions.
0 No effect.
When the interrupt 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 interrupt, it is
important to reset the digital comparator to initial conditions when starting
a new sequence so that stale data is not used.
