Hello,
I am trying to use the SPI interface on the Teensy 4.0 board which has a Cortex M7. I found the registers and there offsets in the RM0444 Reference Manual but can't find the Base Address of these registers anywhere!
Thanks
That's a question for ST - it has nothing to do with ARM.

But, surely, this must be defined in the headers that ST provide ?!
Thank you for replying Andy! I'm a bit hazy on terminology. I'm using the Teensy 4.0. Does that have a STM board inside of it? I assumed the Teensy 4.0 did not have ST parts inside it.
Thanks!

That sounds like an ST document reference.
Always helps to provide links so we know exactly what you're talking about
Remember that the Teensy is not an ARM product.
Andy,
I have a background in FPGAs and I think I must be getting some terminology wrong. Processor does not equal core? I always thought they were the same thing. What components are not included in the "core"? I'm assuming now the peripherals, MCU, ...
The SPI Status and Control registers are in the Cortex-M7 documentation. I would assume that means the components to use SPI are inside the core?

See: community.arm.com/.../158950
I was looking at a ST document thinking it was an ARM document when I really need to be looking at the NXP document.
Thank you for your time and patients!!
