Newbie mitsubishi question

Hi guys,

I have a newbie question about a mitsubishi instruction in a program.

CMP K2M170 K2M180 M150.

So im not really sure how the comparison is done. Compare 2 nibbles starting from M170 with 2 nibles starting from M180 or compare 2 bits starting from M170 with 2 bits starting from 180?

I understand the part where if the value 1 < value 2 => M150 turns on
if val 1 = val 2 M151 turns on, etc.

Thank you

Micky

It's the first way you mentioned.
K2M170 = M170 to M177
K2M180 = M180 to M187

You can use any value K1 to K4 with CMP
You can use any value K5 to K8 with DCMP (Double word compare)
