Re: MPLABX v5.40 PIC18F27Q10 simulator crash when PWM2 enabled
Yep, CCP is broken for 18F27Q10. I've written a bug report which will get addressed at some point in the future.
As to your question about how this gets through testing, its simple: There's no test for CCP for 18F27Q10. There are tests for that CCP, but not for 18F27Q10. There are tests for 18F27Q10, but not against CCP.
