Pretty cool hardware!

Spell out these acronyms. I've been writing some code for the ARM
TCM (Tightly Coupled Memory) and often vendors pick up this terminology
and call all on-chip memory "TCM", though it has a specific technical
meaning in ARM context.

What does TCM mean in your case?
And what is SiTA?
