| #fuses Statement Failed in Mplab 8.15a with CCS compiler |

hello, guys,
I meet another problem in code building in Mplab 8.15a with calling CCS Rev 4.080.
Currently , I use an external 20M crystal as the clock source for PIC24FJ128GA106. And I build a test code for it.
| Code: |
#include "24FJ128GA106.h"
#fuses HS
#fuses NOWDT, DEBUG, NOPROTECT, NOJTAG, IOL1WAY
void main()
{
do
{
#asm
BCLR 0x02C8, #3
BSET 0x02CA, #3
#endasm
}while(1);
}
|
Firstly I set the configuration bits in Mplab IDE manually, Oscillator Select as the Primary Oscillator (XT,HS,EC) and then I got the value for #OSCCON is 0x2200.
Then I click on the Configuration Bits set in code, I got the value for #OSCCON is 0x7700.
Seems the code could not configure it correctly. But it is compiled successfully.
I guess, if the #fuses HS is not recongnized & configured correctly, other #fuses could not be recongnized too.
Of course I could re-configure the SFRs in my code without #fuses statements, but I am wondering whether there are some erroring in it.
Appreciate for anyone's comments.
Regards,

No #fuses statement fails. You didn't specify the correct setting.
You have to set also fuse PR to select the primary oscillator. |

Hello, Frank,
Heartfelt thanks.
I have checked the settings for couples of times. Unfortunately I could not find it. ^_^
BTW, I am wondering how to get the complete & detailed specification for #fuses or other pre-processor statement since I could not get the enough information from the user manual. Some statements other developers used in their code are not listed in the manual.
Thanks & Regards,
Update:
P.S.: I have find the valid #fuses, I would try it later.

And what about the | Code: | | #use delay(clock=20000000, RESTART_WDT) |
statement? |

It's recommended, when using a watchdog and long delays, I think. |
