test with dspic33FJ128MC802 [solved]

[Mgros]

With my C compiler

Code:

//IPC0bits.T1IP = 0;                  //T1IP<2:0>: Timer1 Interrupt Priority bits  111 = Interrupt is priority 7 (highest priority interrupt)
IEC0bits.T1IE = 1;                  //T1IE: Timer1 Interrupt Enable bit
T1CONbits.TCS = 0;                  //0 = Internal clock (FCY)
T1CONbits.TSYNC = 0;
T1CONbits.TCKPS = 0b00;             //TCKPS<1:0>: Timerx Input Clock Prescale Select bits
T1CONbits.TGATE = 0;
T1CONbits.TSIDL = 0;
T1CONbits.TON = 0;                 //TON: Timer1 On bit 1 = Starts 16-bit
TMR1 = 25575 ;

and here is what he does in assembler

Code:

;Robot#3.c,1408 ::                 IEC0bits.T1IE = 1;                  //T1IE: Timer1 Interrupt Enable bit
        BSET        IEC0bits, #3
;Robot#3.c,1409 ::                 T1CONbits.TCS = 0;                  //0 = Internal clock (FCY)
        BCLR        T1CONbits, #1
;Robot#3.c,1410 ::                 T1CONbits.TSYNC = 0;
        BCLR        T1CONbits, #2
;Robot#3.c,1411 ::                 T1CONbits.TCKPS = 0b00;             //TCKPS<1:0>: Timerx Input Clock Prescale Select bits
        MOV        #lo_addr(T1CONbits), W0
        MOV.B        [W0], W1
        MOV.B        #207, W0
        AND.B        W1, W0, W1
        MOV        #lo_addr(T1CONbits), W0
        MOV.B        W1, [W0]
;Robot#3.c,1412 ::                 T1CONbits.TGATE = 0;
        BCLR        T1CONbits, #6
;Robot#3.c,1413 ::                 T1CONbits.TSIDL = 0;
        BCLR        T1CONbits, #13
;Robot#3.c,1414 ::                 T1CONbits.TON = 0;                 //TON: Timer1 On bit 1 = Starts 16-bit Timer1
        BCLR        T1CONbits, #15
;Robot#3.c,1415 ::                 TMR1 = 25575 ;
        MOV        #25575, W0
        MOV        WREG, TMR1

And when I use the interrupt

Code:

void T1Interrupt() iv IVT_ADDR_T1INTERRUPT{

//...Code

//TMR1 = 25575;
TMR1 = 0;

//RAZ Timer1 Interrupt Flag Status bit
IFS0bits.T1IF = 0 ;
}

And when I use the interrupt in asm

Code:

;Robot#3.c,574 ::                 void T1Interrupt() iv IVT_ADDR_T1INTERRUPT{
;Robot#3.c,578 ::                 TMR1 = 0;
        CLR        TMR1
;Robot#3.c,581 ::                 IFS0bits.T1IF = 0 ;
        BCLR        IFS0bits, #3

Thank you for the attention ... and see you soon ... bye and sorry for my english again ^^
