how to make the XET256 enter a full stop mode?

my problem is the MCU execute the "asm stop",but MCU dont enter the stop mode. and The"asm ANDCC #$7F" instruction is also executed before.

and i found: the first time run the sw in the codewarrior debugger,the condition is ok,mcu didnt enter the stop mode,but when i  reset target,and the second run the sw,the condition is ok,the mcu enter the stop mode.

why?please tell me ! thanks!

Isn't XGATE running or set up with fake XGATE activity enabled?

I didnt use XGATE ,Just use the the only single core (9cs12),Now i found MCU can enter stop mode ,but the IRQcant wake it.  May be the interrupt happened many times ,the MCU can wake. WHY?
