How i can measure time with 8051 timers tf0

Web24 feb. 2005 · Your code can read the TF0 bit at any time to find out if the timer has overflowed. You can also configure the Timer 0 interrupt to automatically execute code when the timer overflows. When the interrupt code … WebWhenever a timer overflows from it’s highest value back to 0, the microcontroller automatically sets the TFx bit in the TCON register. This is useful since rather than checking the exact value of the timer you can just check if the TFx bit is set. If TF0 is set it means that timer 0 has overflowed; if TF1 is set it means that timer 1 has ...
