18F2580 with strange behaviour when using Hserin and RX interrupt

[richard]

if I change to Define Osc 32 the code will run slower (tested before with pause 1000 and led blink). Weird things happen with this 18F2580 MCU

pll only works with primary clock sources , if you set the int-osc as primary clock then it works as expected

DEFINE OSC 32


    OSCCON =% 01110000 '8MHz INTOSC 
    OSCTUNE=% 01000000 '

Hi Richard,

you are correct (as always)!
I thought we had to choose internal insteal of primary since it's set to an internal osc.
