Bits 0, 1 – STARTn Comparator n Start Comparison (n=0,1)

Writing a '0' to this field has no effect.

Writing a '1' to STARTn starts a single-shot comparison on COMPn if both the Single-Shot and Enable bits in the Comparator n Control Register are '1' (COMPCTRLn.SINGLE and COMPCTRLn.ENABLE), if enabled in single-shot mode. Writing a '1' has no effect.

This bit always reads as zero.

Note: If COMPCTRLn.SINGLE=1 and WINCTRL.WIN=1, window single shot mode, it is only necessary to set one of the CTRLB.STARTn bits for the paired window comparators.
