Register 47: ADC Digital Comparator Reset Initial Conditions (ADCDCRIC),
offset 0xD00
offset 0xD00
This register provides the ability to reset any of the digital comparator interrupt or trigger functions
back to their initial conditions. Resetting these functions ensures that the data that is being used by
the interrupt and trigger functions in the digital comparator unit is not stale.

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

Digital Comparator Trigger 7
Description
Value
No effect.
0
Resets the Digital Comparator 7 trigger unit to its initial
conditions.
conditions.
1
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. After setting this bit, software
should wait until the bit clears before continuing.
