#157977 - this may, some day, bite you in your lagest muscle
Responding to: ???'s previous message
The timer is not been activated (until setb tr0) so enabling interrupts before programming timers is not a cause of worry.

so many things are "not a cause of worry" NOW but may, some day, bite you in your lagest muscle. As a general rule NEVER activate interrupts till ALL initialization is finished.

Some day you add some other initailize code where the interrupts enable IS "a cause of worry" and will have a nice debugging session to find out that you activated interrupts before ALL initialization was finished.
