Processor Architecture Registers vs. MCU Registers


I am currently learning about microcontrollers and processors, and I have a couple questions about some distinctions between the two. As I understand, the MCU contains a processor that implements a processor architecture. For example, I am using a SAML22 Microcontroller that has a ARM Cortex M0 for its processor. So it would have the following:

Architecture - ARM

Processor - ARM Cortex M0

MCU - SAML22

Are the registers that I gather from the SAML22 data sheet related to the ARM Cortex M0? If so, how?


Solution

  • No, the microcontroller datasheet describes peripherals which are not part of the ARM core.

    The SAML22 has a Cortex-M0+ core, which is described in ARM documents "Technical Reference Manual" (TRM, DDI0484) and the less detailed "Device Generic User Guide" (DGUG, DUI0662).
