Please help me to understand the timer interrup , actually i am new in mc...

I know timer is used to get delay in mc . but i'm in confusion about timer interrupt.

i just want to know that how it work . means what does it do. Is it also used to generate delay or something else....

Timer interrupts are nothing but a notification that timer register has overflown. Say your timer register is 8 bit, so when there is a change of value from 0xff to 0x00 there will be an interrupt signal generated.
Yes you can use it to generate precise delays.

If you want to execute something periodically, place that in timer interrupt.

If you are using PIC dsPIC, PIC32, AVR micro-controllers then use this tool to generate code and try to match it with your setup
