SPC700 Instruction Set Effective Address Regions (Attempt 2)

So apparently I'm not allowed to mention certain 20 year-old documents or the Nintendo boogeyman is going to come kill me, my family, and the folks that host this site. SO I made my own diagram:

Can someone please verify that I have the effective addresses correct for these addressing modes?
Thanks!

Looks correct.
Just note that the direct page addressing modes wrap within the same page. So the effective address range will be 0000H-00FFH / 0100H-01FFH depending on the direct page flag.

That's a great point. I'll update the diagram to explain this. Thanks!

Don't forget the stack, with address range 0100h-01FFh.
