MC9S12XEP100 opcodes / instruction set

Hi!

 

I am reviewing some code for the MC9S12XEP100 MCU and I am wondering where to get the correct Assembly instruction set? I have tried the "CPU12 Reference Guide (for HCS12 and original M68HC12)", but I can't find the opcode SYS from this document.SYS appears in the code I'm reviewing.

 

There must be a better, maybe a more recent instruction set document for this MCU. I just can't seem to find it...

 

BR,

Timo
