16 bit PWM using CCP1

[Normnet]

PIC18F2331/2431/4331/4431:

FOSC 40 MHz
MIPS 10
PWM Resolution 14 bits
PWM Frequency 2.4 kHz

14 bit to slow for CD quality music.
10 bit sounds good though.

A dsPIC would be ideal.

On my first post my code included saving the state of the critical registers.
Would this be required in a longer program?

Maybe you'd be better off with an R2R network as a Digital to Analog Converter.

Something like what Steven Wright did here (Not PBP).

And no, you won't need to save STATUS, WREG and BSR, unless you start using Low Priority interrupts.
The Shadow registers automatically save and restore them in hardware for High priority ints on 18F's.

Now would like to port to PBP a basic PWM low pin count low part count wave player.
The code is 8,069 program bytes possibly less if optimized.
Are their < 28 pin 18F PICs supported by compiler 2.50C?
