WebThis chapter will begin with an examination of the timing issues involved with multiple interrupt sources. Next it will explore how to use a single interrupt source and then multiple interrupt sources. The PIC18F452’s two interrupt priority levels will be examined. Working together, they can reduce the latency for a high-priority interrupt. WebTo generate 5ms interrupt we require (5/1000)*1M ticks = 5000 ticks. Since our timer is in 8bit mode. It can only tick up to 256 ticks. So we must use a presaler. If prescaler is 1:4, then ticks required are 5000/4 = 1250. Still larger than 255. if prescaler is 1:32, then ticks required are 5000/32 = 157.
