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 ...

Just bear in mind that Intel's Panther Lake has a bit of FRED, too.

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...

For most UNIX systems, Linux included, device drivers typically divide the work of processing interrupts into two parts or halves. The first part, the top half, is the familiar interrupt handler, ...

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 ...

A computer cannot meet its requirements unless it communicates with its external devices. An interrupt is a communication gateway between the device and a processor. The allocation of an interrupt ...

Understanding RISC‑V traps is essential for Chip Designers building RISC‑V CPUs, microcontrollers, and complex SoCs. It’s equally important for Embedded Engineers who develop and debug software stacks ...

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 ...

Every time a computer receives a network packet, completes a disk write, or a user moves the mouse, the processor handles an event known as an ...
