C6748 Timer Interrupt

I will try to use the Timer Interrupt. I made sure that the Timer is running and interrupt occur.

Register bit PRDINTSTAT34;12 in INTCTLSTAT is 1; Interrupt has occurred.

I saw the following methods to try.

- Use Timer0 32bit unchain mode.

- PRD = 0x50000

- TMR0_INTCTLSTAT |= 0x00010001;   // enable timer0 12, 34 interrupt 

- INTMUX1 = 0x00400400; // use INTSEL5, INTSEL6

and intvct.asm file add to project

intvect.asm as follows.

; Global symbols defined here and exported out of this file

   .global _intcVectorTable

   .global _c_int00

   .global _TIMER0_TINT12_isr

   .global _TIMER0_TINT34_isr

   .global _vector3

   .global _vector4

   .global _vector5

   .global _TIMER1_TINT12_isr

   .global _TIMER1_TINT34_isr

   .global _vector8

   .global _vector9

   .global _vector10

   .global _vector11

; This is a macro that instantiates one entry in the interrupt service table.

VEC_ENTRY .macro addr

    STW   B0,*--B15

    MVKL  addr,B0

    MVKH  addr,B0

    B     B0

    LDW   *B15++,B0

    NOP   2

    NOP

    NOP

   .endm

; This is a dummy interrupt service routine used to initialize the IST.

_vec_dummy:

  B    B3

  NOP  5

; This is the actual interrupt service table (IST).

_intcVectorTable:

_vector0:   VEC_ENTRY _vec_dummy      ;RESET

_vector1:   VEC_ENTRY _TIMER0_TINT12_isr    ;NMI

_vector2:   VEC_ENTRY _TIMER0_TINT34_isr    ;RSVD

_vector3:   VEC_ENTRY _vec_dummy    ;RSVD

_vector4:   VEC_ENTRY _vec_dummy  ;isr0

_vector5:   VEC_ENTRY _vec_dummy  ;isr1

_vector6:   VEC_ENTRY _vec_dummy  ;isr2

_vector7:   VEC_ENTRY _vec_dummy  ;isr3

_vector8:   VEC_ENTRY _vec_dummy

_vector9:   VEC_ENTRY _vec_dummy

_vector10:  VEC_ENTRY _vec_dummy

_vector11:  VEC_ENTRY _vec_dummy

Also ISR was used as follows.

void TIMER0_TINT12_isr(void)

{

Tmr_test1++;

}

void TIMER0_TINT34_isr(void)

{

Tmr_test2++;

}

But Tmr_test1,2 is not increase. 

How to use Interrupt service routine? 

Someone cna help me!

Thanks.
