Bits 1:0 – STARTx: Comparator x Start Comparison
Writing a zero to this field has no effect.
Writing a zero to this field has no effect.
Writing a one to STARTx starts a single-shot comparison on COMPx if both the Single-Shot and Enable bits in the
Comparator x Control Register are one (COMPCTRLx.SINGLE and COMPCTRLx.ENABLE). If comparator x is
not implemented, or if it is not enabled in single-shot mode, writing a one has no effect.
Comparator x Control Register are one (COMPCTRLx.SINGLE and COMPCTRLx.ENABLE). If comparator x is
not implemented, or if it is not enabled in single-shot mode, writing a one has no effect.
This bit always reads as zero.
