Answer Posted / kumar
ISR is interrupt service routine. it is seperate code
written some where in the memory. if any interrupt comes
mp checks the priority of the interrupt and service it
meanwhile the content of the progaram counter value is
written in stack after executing isr ,execution transferred
to main program.
FUNCTION CALL is seperate thing. function call is seperate
code that has to be written at the end of function . for
example, in some programs we want to perform one operation
repeatedly at that time we perform that operation by
calling that function instead of writting many times.
