Re: PIC16LF1823: How to know when the external oscillator is stable
The OST is disabled in EC mode but it might be possible to insert a fixed delay from ext oscillator turn on to clock switch to allow the external oscillator to be stable. OST is available with HS, XT and LP mode of operation. HS in single ended mode might work but I think it would require the other oscillator pin to be open. This seems risky to run this way.
