The sequence of importance assigned to interrupts. If two interrupts occur simultaneously, the interrupt with the higher priority is serviced first. In some systems, a higher-priority interrupt can ...

We love interrupts in our microcontroller projects. If you aren’t already convinced, go read the first installment in this series where we covered the best aspects of interrupts. But everything is not ...

Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to ...

This application note presents the RX family of microcontrollers on using multiple interrupts. The document includes the specifications, the operation confirmation conditions, the hardware and ...

A priority interrupt controller is a hardware designed chip which acts as an overall system manager to efficiently handle the multiple interrupts that tend to occur from the varied number of ...

What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...

As a fully preemptive kernel, SST must ensure that at all times the CPU executes the highest-priority task that's ready to run. Fortunately, only two scenarios can lead to readying a higher-priority ...

When a WFI instruction is executed or when the processor enters sleep mode using the Sleep-On-Exit feature, the processor stops instruction execution and wakes up when an (higher priority) interrupt ...

Performance is a topic that never strays far from the mind of most embedded systems developers. However, relatively speaking, many of us have it easy. We develop soft real-time systems in which a few ...
