"Webprogram context before executing the interrupt handler. If the processor is performing this context-saving operation when an interrupt of higher priority arrives, the processor switches directly to handling the higher-priority interrupt when it is finished saving the program context. Then tail-chaining will be used prior to executing the IRQ_B " - Tail chaining interrupt

WebAll interrupts are serviced in low latency since NVIC is closely associated with the core. NVIC also supports some advanced interrupt handling modes including Interrupt preemption, tail chaining, late arrival. These are the reasons why ARM has low latency and robust response. Web21 Apr 2024 · The subtle, and critical statement is about the priority of the pending interrupt in the group that could cause tail-chaining. This must be a higher priority that the completing interrupt for the process to occur. The reason for this design is not explained by Arm, but is obvious after some thought:

WebTail-chaining can occur before the TIM interrupt and NVIC state propagate. Clear the state early, and have fencing operations so the write-buffers vacate. perhaps try unkn_sr ... Anyway the tail-chaining logic in the NVIC is making its decision a lot earlier than the bubble through on the TIM->SR write side. WebInterrupts are a commonly used technique in microcontrollers allowing CPU-external systems to indicate need for change in CPU execution. Instead of using polling loops to …
