1. Introduction to Cortex-M0 Processor Core Exception Interrupts The Cortex-M0 core is equipped with an exception response system that supports numerous system exceptions and external interrupts. Among them, numbers 1-15 correspond to system exceptions, while numbers greater than or equal to 16 are all external interrupts. The smaller the numerical value of the priority, the … Read more
This article is reproduced from the Jishu Community Jishu Column: Agile MM32 MCU Each external interrupt has a corresponding priority register. The Cortex-M0 has a total of 8 NVIC-IPR registers, with each register managing 4 IRQ interrupts. Therefore, the M0 supports a maximum of 32 IRQ interrupt sources, plus 16 core interrupts, which means the … Read more
