| Help BUG in #INT_DEFAULT |

PCWH 3.218
I am using interrupt comparator by #INT_DEFAULT
( The wizard doesn't function and Device Edit wrong memory location!)
I know the #Int_default has a bug!!( My application does't function....)
I can update my complier the next month only!
The bug is fixed by next release
3.219 A bug in #INT_DEFAULT is fixed affecting code located outside page 0
I have 3.218 , somebody can help me?
Thank |

| Write your own #int_global handler and check the bits yourself. Search the board for examples. |

So, what is your problem? You have one month of of update time left, and v3.219 has been released. What is stopping you from downloading this version?
Are you sure the above bug fix will solve your problem?

This might fix your problem with the 'Device Edit wrong memory location'.
Or....
Post your code and we will have a look at it. |

My is an annual update. I am not secure for 3.219
I am using #INT_global only for comparator interrupt (C2).
The other interrupts are disabled, but the program counter jump always to location 0004h
#INT_GLOBAL
void isr() {
#asm
MOVWF save_w
SWAPF status,W
BCF status,5
BCF status,6
MOVWF save_status
#endasm
if(C2IE_BIT) // Is the interrupt enabled ?
{
DAC=100; //for debug
if (MC2out==0) // or C2IF_bit
{
C1ON=0;
C2ON=0;
Fan Off
SMCON =0 ;
}
DAC=51; // for debug
C2IF_BIT=0;
}
#asm
SWAPF save_status,W
MOVWF status
SWAPF save_w,F
SWAPF save_w,W
#endasm |

So, where do you expect the program counter to go?. 0004H, is where an interrupt will vector to. This is correct...
Your code is 'fussy'. If you only have the C2 interrupt enabled, the only way the code can be reached is by this interrupt, hence there is no need to test for the interrupt enabled bit. However if any other interrupt can be enabled, then you _must_ clear the interrupt flag for this before exiting the routine, or the code will be stuck in an infinite loop, constantly jumping back to address 4. It sounds as if this may be what is actually happening to you.
You also need to look through the entire assembler generated for the interrupt, and verify that no other registers are used by your code, and if any are, save their contents. You are saving W, and status, but if (for instance), 'Fan off' involves accessing an array, then the pointer registers will also need to be saved. As soon as you use int_global, you become responsible for saving everything, and must check just what is needed.
If you cannot see what is happening, post the definitions you are using for all the interrupt flags/registers, the definitions for 'fan off', the definitions of the numeric values used, what processor is involved, and the code you are using to initialise the interrupt.
