Complete register and programming reference for RT1020?

bobbyk — Tue, 03 May 2022 18:07:29 GMT

Where can I find a complete register reference for the RT1020 series MCUs? Specifically, I’m looking for information on NVIC priority registers and the best way to access them. I’ve seen references for LPC series MCUs to NVIC_IPRx registers and SetInterrupt_Priority() function, but I cannot find any similar reference for RT1020.

As the NVIC is an ARM-IP you will find the documentation in the ‘ARM Cortex-M7 Processor Technical Reference Manual’ (--> https://developer.arm.com/documentation/ddi0489/b/nested-vectored-interrupt-controller/nvic-functional-description).

Best way to access it is via the CMSIS library from ARM

Hi @bobbyk

You can find the file from the SDK:

SDK_2_11_0_EVK-MIMXRT1020\CMSIS\Core\Include\core_cm7.h
