Fuse Config for PIC18F1320

[ritchie]

Hi,

#include <18f1320.h>
#device ADC=10
#fuses ?????
#use delay (clock=4000000)

What would be the proper fuse configuration of a PIC18F1320 using the internal oscillator of the chip for a 4MHz clock frequency?

I understand that 18f1320 has a max internal oscillator of 8MHz? what config do I need to use this clock frequency?

Thnx

I need to keep up better with the new chips! I like this one. Because I was interested, I read a bit of the data sheet.

In particular, see data sheet 39605b.pdf, sections 2.1 and 2.6.

It appears that you need either INTRC or INTRC_IO (which the data sheet calls INTIO1 and INTIO2) to use the internal oscillator, in addition to the other settings you need for the watchdog timer, power-up timer, etc.

There's also a reference to a setup_oscillator() function in the device header file (18F1320.h) and constants for everything from 31 kHz up to 8 MHz. I didn't see any other documentation for this, but
