does this help anyone?

it has all the instructions and architecture info. It may be redundant. I dunno.

i think i printed this out.......friggin a lot of pages.....

Did anyone get the NX-8/200 instruction set manual? I dunno how different the NX-8/500S core is from it.

(Forget it, it is compatible duh)

I couldn't find info on timers and A/D configuration. Anyone has it?
I'm reading the rom code from 000h address so I'm facing these registers and idk what the code is doing with them.

So there are three different documents for the 66k processors:

• The instruction set reference. It tells you how the assembly instructions work. Thats what this nx800 core doc is.
• The data sheet. Basic data about how much memory, memory architecture, etc.
• The instruction manual. It has info about how the timers work, how AD converters work, etc. This can be found for the 201 at http://85.119.8.130/honda/chip/Oki_66201_Instruction_Manual.pdf or http://85.119.8.130/honda/chip/Oki%2066201%20Manual.zip. Partial scans of the 301 are inanother post, but mostly it should behave similar to the 201. If those go down I have copies, so let me know.
