You might check out the Visual Device Initializer from Microchip. This is an add-on tool to MPLAB which allows you to set up peripherals, such as the PWM, by specifying operating parameters. It doesn't support every part yet, but does the 18XXX and the dsPIC parts. Code for the 18XXX could probably be fairly easily converted to run on the 16XXX parts.
Does the PIC family have a minimum clock speed ? What happens if you run the PIC lower than it ?

All currrent members of the PIC family are fully static CMOS, so there is no minimum clock frequency.
A good way to go might be either an 800 or 640kHz ceramic resonator.

I remember a time when static and CMOS didn't play well together ;)
Were there CMOS dynamic chips? The ones I can think of were p-MOS or n-MOS.

He was cracking wise. CMOS is inherently a static logic technique.

Modern DRAMs would be called Dynamic, and IIRC the first 80C51 CMOS variants shipped with a 3.5MHz min clock speed - some portions were dynamic. Infineon makes a high end uC, with DRAM on chip. Any 8 bit uC used today would be Static CMOS process.
