The timer is not been activated (until setb tr0) so enabling interrupts before programming timers is not a cause of worry. You mention that you don't start the timer until fully initialized. But you imply that you want to regularly change the timeout value (your code has a label "Update:" and the comment "routine to change the value of r0 and r1") and don't understand why you should stop the timer while reloading it. How does that go with your original question: "Is it necessary to use the instructions clr TR0 and setb TR0 to resart the timer with new timer values"? |
