    I am fairly new to assembly language and using Dspic's. The following is a program that I have been working at for quite awhile.

    "Write a program for timer, the timer is working as counting mode, and its main subroutine will display its counted value on PORTB.
    Every 5 pulse from outside, it will trigger the timer interrupt, then its interrupt subroutine will toggle PORTA.0 five times"

    I have been unsuccessful making the value display on PORTB., and I am unsure how to implement the interrupt on the 5th pulse from the outside.
    At the moment I am trying to use timer1 as an Asynchronous counter, which the interupt will toggle PORTA.0 five times.

    Any help or suggestions would be appreciated.
    Thank you.
