The 8253 has no specific interrupt pins and therefore the timer OUT pin is often used to generate an external interrupt signal. With the IBM PC, this is done by connecting the OUT signal from timer/counter 0 to the IRQ 0 signal and setting the timer/ counter to run in mode 3 to generate a square wave. WebTo generate a timed wave (such as square wave or periodic pulse), the 8254's three CLK inputs (pins 9, 15 and 18) need to be driven by a known "ground truth" pulse. This is what the oscillator (see Figure 6) does. This 4-pin silver rectangular shaped part generates square waves at its rated frequency. palm beach county critical race theory
