PBP array in ASM statements

[mister_e]

...nevermind... keep thinking...

[pedja089]

The same is happening with @ CLRF _Counter +1.
And ISR stops, sometimes begins to run, sometimes I have to reset my pic

[mister_e]

I'm tad rusty, for ease... I would bet your should assign your array to BANK0 instead...

post your PIC model and code, we'll try to help

Here it is ISR

if PIR2.1=1 then
   T3CON=%00000110
   Wp= Wp & uwp
   Xn.0=IN1
   Xn.1=IN2

   
   IF (Xn.0<Xs.0 AND Trf=0) OR  (Xn.0<Xs.0 AND Xn.1=1 AND Trf=1) THEN
@     INCF _Counter,F 'this work
      IF Counter[0] = Mtp2[0] OR (Counter=256 AND Mtp2[0]=0)THEN
@      CLRF _Counter ' and this
          CNT[0]=CNT[0] + Add[0]
      ENDIF
   ENDIF
   
   IF (Xn.1<Xs.1 AND Trf=0) OR (Xn.0<Xs.0 AND Trf=1 AND Xn.1=0) THEN
@     INCF _Counter+1,F 'Counter[1] = Counter[1] + 1  'won't work
      IF Counter[1] = Mtp2[1] OR (Counter[1]=256 AND Mtp2[1]=0)THEN
@      CLRF _Counter+1'Counter[1]=0 'won't work
          CNT[1]=CNT[1]+Add[1]
      ENDIF
   ENDIF
   Xs=Xn

@  CLRF PIR2
endif

Pic is 18LF14K50
EDIT:
bank0 or bankA is same...
I tried RTC,it works fine with both.

[mister_e]

weird... a simple loop works here,

start:
    asm
        incf _MyArray,F
        incf _MyArray+1,F
    endasm    
    myvar=myarray[0]
    myvar2=myarray[1]
    goto start

but as you're using a blend mix of ASM and PBP in an ISR, you must make sure you're always on the good BANK case not, hell yeah it may goes to lalaland... what you could try is to set all variable that goes in the ISR to BANKA.

And yes I know I miss something

EDIT: The more I think, the more it looks like a bank switching issue,

    MyArray VAR BYTE[8] BANK1
    
    MyVar var byte BANK0
    MyVar2 var byte BANK0
    clear

start:
    asm
        CHK?RP _MyArray
        incf _MyArray,F
        incf _MyArray+1,F
    endasm    
    pause 500
    myvar=myarray[0]
    myvar2=myarray[1]
    goto start

The above work... commentout the CHK?RP line.. and nope... it doesn't.

And NOPE, BANK0 !=BANKA

BANKA   $0000, $005F
BANK0   $0060, $00FF

Finger crossed before the real ASM/Compiler gurus came here and slap me a good one

[pedja089]

As you can see, my isr have both and asm and pbp... All variables is in bankA.
Somewhere i read that bank for 18F doesn't matter...
How to setup correctly banks?
But if I use i = i +1 instead INCF everything works. INCF and CLRF work if I make a array to separate variables...

[mister_e]

Since we don't have the full code, or .LST file, I'll leave the more in deep & technical explanation of Access Ram, BSR and plah plah plah of section 3.3.3 to better guys (I hope I'm right though ).

Again, the compiler keep track of everything for you, hence why the PBP lines will always works.

add
@ CHK?RP _Counter
just before your INCF, DECF and or CLRF to see what happen
