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.
