GXWorks2 - K8M300?

[d4rkm4n]

Hi,

I found this instruction on this ladder and wondering how it is calculated?

From the right, I understand they compare value from M0-M31 to M300-M331 because they started next with M32/M332.

I thought it K8 * 8bit = 64 but it is not. 

 

 

Thanks!

Nibbles not bits. K8 = 8 x 4 = 32

Thanks for your reply.

Why x 4? Any reason? Applied to D, X and Y as well?

Yes, because it is written in the manual. K1 means 4 bits. And as you can see from your example, it is valid also for D registers. Of course also for X, Y and M.
