Thanks Dave!
Very interesting! So if I understand correctly, a 20 MHz external crystal with your line of code (thank you for this) will give an internal CPU speed of 40 MHz? By the way I like your idea of a "water cooled" PIC!

Just curious since I have been away from all this for so long, in the past when you programmed your PIC you would have to specify either XT or HS depending upon what frequency resonator you used. It appears this is now "built-in" with a default of XT? (__CONFIG _CONFIG1H, _XT_OSC_1H).

It is correct to assume with HSPLL the multiplier is always X4?


Best, Ed
