hello

I am using two interrupts in my program,one is reception interrupt and one more is timer interrupt.
I am using timer interrupt for generating PWM waveforms.I want to give priority to timer interrupt.so i have to make timer pripority inerrupt bit high.Other then this setting any other setting i have to make or it's not required
 

Using 2 Interrupts

Set your IVT first..that way you could priortize your interrupts..
 

Re: Using 2 Interrupts

What microcontroller are you using?
If the uC has a compare/ PWM generation unit, it can generate the PWM with a duty cycle determined by the value in the compare unit registers. In this case, you don't need interrupts for the PWM generation, you need only to set the compare/PWM value in your program.
But if you generate PWM in software you may need some interrupt. To set a priority, you can globaly disable the interrupts in the service routine that has priority.
