opcodes for movi

RS_Jim

Hi,
I was recently frustrated by trying to get the correct opcode information to use in a MOVI instruction so I built the following table:

{{opcodeconstants.spin is a table of opcodes that can be used in conjunction with
the MOVI command for self modifing code. This table can be cut and pasted into the
spin code for a PASM object or used with the file include function of bst. }}

I am finding having this around is rather usefull. I hope is usefull to others.
