Update 68000 function bindings in doc so they work with 68000 #19

Open vinz6751 opened 3 years ago

The function bindings in the manual make use of lea <ea>,Dn , but this not supported on the 68000 (only from 68020 probably?), on the 68000, LEA's destination register must be an address register.

So we have to use:

move.l #buffer,d0 if using an immediate address
otherwise go through an address register e.g.
```
lea.l (a0,d6),a6
move.l a6,d0
```

I can do the update in a few days hopefully.

Oh good catch. Foolishness on my part, and maybe a copy-paste mistake. I may go ahead and fix these tonight.

pweingar commented 3 years ago

I have updated them (I think). Take a look sometime and let me know if it looks right now. I really should have used working examples.

vinz6751 commented 2 years ago

Thanks for the update, the example for sys_fsys_open on page 24 still needs adjusting. The rest looked fine

pweingar commented 2 years ago

I've updated sys_fsys_open.
