P1 Instruction Set Summary

Cluso99

While I was doing the P2 Instruction Set Summary I thought I may as well do one for the P1. (not sure if I have done this before)

Postedit: corrected errors from following post. Added color pic.

There are several errors in your instruction summary. CMP is just a SUB NR, similarly to how TEST and TESTN are just AND NR and ANDN NR . You have ADDABS where SUBABS should be, and you have CMP where ADDABS should be. You say that the R bit for ADDX and SUBX is always 0, because they're in the same group as CMPS and CMPSX (for which the R bit is always 0), which is certainly not true. Also, you say that the R bit for the WAITxxx instructions is always 0, but for all four of them, setting it to 1 causes it to do dest += src (this is mainly for WAITCNT, but it works for all of them). You do the same thing for COGINIT - you need to set R to 1 to figure out what cog was started in a cognew.

Electrodude,
Thanks for finding errors. I will update the first post with corrections shortly done.
There were some shortcomings with my spreadsheet which automatically does a lot of this work for me (for the P2).
