Bit 27 – FLTINJ Fault Injection bit

A write of ‘1’ to this bit will simulate a comparison mismatch event. The ERR bit will become set, the ERRCNT will increment to EOVFV and the OVF will be set if the ERRCNT overflows.

Bit 26 – OKINJ OK Inject bit

A write of ‘1’ to this bit will simulate a transition on the reference signal input, blanking time insertion and a good comparison between reference and feedback signals. The OK bit will be set.
