hai sir,
           can any one please  tell me the difference between polling and interrupt mechanism in any 16 bit microcontroller.currently i am using MC9S12XDp512 .how the polling mechanism is handled and how is it different from interrupt handling.while hadnling data transfer how polling mechanism is handled and how is it different from interrupt handling.in polling mechanism how an array of 8 elements tranferred and in interrupt mechansim how they are transferred and reception side how they are recieved just tell me the procedure of handling of both mechanisms .what i am thinking is if i tranfer data from one microcontroller to other microcontroller through polling mechnaism only one element is recieved at a time and in interrupt mechanism all 8 elements are recieved when interrupt comes is it true please ealborate and tell me
 
bye
