![]() ![]() That's about as much help as I'm going to be for that portion. For what it's worth, it does appear the hex designation is the same. They also added 6 extra instructions including a sleep (slp). I think Hitachi licensed the 6800 architecture and adapted it for industrial and hardened environments. Update: Came across this wikispace on the 6800 and it also lists a Hitachi 6301 controller version. I do a quick comparison of the accumulator A ADD instruction (ADDA) and it appears to me that they have the same hex designation in all the five addressing modes. Then open this link for the Motorola instruction set Here is my reasoning for thinking this, please sanity check this out:įrom the HD6301V1P datasheet, go to scanned page 63 (23 in your pdf reader) and look at table 8 where the opcodes are listed. Hitachi may have licensed this and produced their own chips. If this is true, there should be assembler/editor programs. So looking at this, I am thinking that the CPU instruction set is based upon the Motorola 6800. ![]()
