Hello everyone

I'm trying to use Instant Interrupts with the PT_INT interrupt (PWM time base) in my code.

I'm using a 18F2431 with a 40MHz clock frequency. My PWM interrupt frequency is about 15kHz (PTPER=333).

With a code like that (with no interrupt, just waiting the PIR3.4 flag in a loop), it works very well :

Code:
DEFINE OSC 40

' PCPWM registers configuration                                     
PTCON0=%00000010        
PTCON1=%10000000
PWMCON0=%01000000
PWMCON1=%00000001
DTCON=%00110110
PTPERH=$1:PTPERL=$4d

' PWM ISR
pwmint:

' Wait PIR3 interrupt
while PIR3.4=%0
wend
PIR3.4=%0
.
.
.
(there is my PWM code)
.
.
.
GOTO pwmint
However, this code below should give me the same results and execute my PWM ISR at each PWM pulse, but it doesn't work :

Code:
DEFINE OSC 40

INCLUDE "DT_INTS-18.bas"     ' Base Interrupt System
INCLUDE "ReEnterPBP-18.bas"     ' Include if using PBP interrupts

' PCPWM registers configuration                                     
PTCON0=%00000010        
PTCON1=%10000000
PWMCON0=%01000000
PWMCON1=%00000001
DTCON=%00110110
PTPERH=$1:PTPERL=$4d

ASM
INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler   PT_INT,  _pwmint,   PBP,  yes
    endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM

@ INT_ENABLE PT_INT

' PWM ISR
pwmint:

' Wait PIR3 interrupt
PIR3.4=%0
.
.
.
(there is my PWM code)
.
.
.
@ INT_RETURN
I need help thanks
