18F4620 Fuses configuration

Hello,

I need help to insert some fuses configurations in my program !
Today my program is OK but only with 4MHZ cristal, because it is the default of PBP. However, I would like to use a 20MHZ cristal and also change WDT and BOR fuses to OFF.
Please, can somebody help me ? I am using a USB programmer, but diferent of ICPROG, I can not to change the fuses in moment of programation. I want to insert it in my PBP code.

I have been used it with sucess to 16F628A for example, inserting :
@ DEVICE pic16F628a, HS_OSC ' System Clock Options
@ DEVICE pic16F628a, WDT_OFF ' Watchdog Timer
@ DEVICE pic16F628a, PWRT_OFF ' Power-On Timer
@ DEVICE pic16F628a, BOD_OFF ' Brown-Out Detect
@ DEVICE pic16F628a, MCLR_ON ' Master Clear Options (External)
@ DEVICE pic16F628a, LVP_OFF ' Low-Voltage Programming
@ DEVICE pic16F628a, CPD_OFF ' Data Memory Code Protect
@ DEVICE pic16F628a, PROTECT_OFF ' Program Code Protection

Now I want to do it with 18F4620!!!

Thanks

You can use back the previous code. Just replace pic16F628a with pic18F4620.

Not quite right Pic2008...

18F PICs require you to use the MPASM Assembler... and MPASM does not recognise the @ DEVICE syntax that configures the Config Fuses in the same way that the default PM Assembler does. Here is an example for a PIC18F2420...

Code:
