Most microcontrollers have input pins that can be configured as interrupts, and these will be edge- or level-sensitive, sometimes programmable as either. Depending on the MCU, a pin configured as edge sensitive may be able to detect rising, falling, or both edges. WebTo use interrupts in a microcontroller, you need to configure the interrupt source, such as setting the pin mode, enabling the peripheral, or selecting the edge or level trigger.

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. WebWhen the interrupt source follows the processor clock it is said to be a synchronous interrupt source and when it does not follow the processor clock it is said to an asynchronous interrupt source. See figure 1.1. Figure 1.1 Asynchronous and synchronous interrupt sources Note: Internally all interrupts presented to the ARM core are synchronous.
