hello guys

I'm trying to use the dspic30f4013 with its fast internal clock (FRC) and with the right configuration to get it run in 30MIPS.

The problem is that there is no information in the datasheet which gives a basic circuit of that (like it was done when we use RC or crystal).
 

Being internal involves that the oscillator doesn't use any external circuit.

i know that, and i know that for some configuration the OSC2 pin could be used as I/O pin, but there is no information about OSC1 pin.

It's clearly specified that OSC1 has no second function. The only point you may be possibly missing is a suggestion how to connect OSC1 in FRC mode. I presume it's no so important, but I would connect it to ground.
 
Are you sure about connecting the OSC1 to ground ?
