FCMEN is the Clock FailSafe Monitor for EXTOSC. If your crystal oscillator fails, FCMEN will revert to INTOSC, for safety sake. If you aren't running EXTOSC, you don't need FCMEN. It probably...

Re: PIC16F15355 config setting to work on internal OSC with clock 4MHz
My understanding is that "FCMEN_ON" is only needed with an external oscillator. If it fails, the PIC reverts to INTOSC.
Also, if you just configure your OSCCON1 for 32 MHZ, you can then select 4...
