Hi KDN,

I don't think you use GetWord()  in a right way.

you need use GetWord() as below:

  byte If_ok;

  word mydata;

  If_ok = IEE1_SetWord((IEE1_TAddress)0x100000,0x1234);

  If_ok = IEE1_GetWord((IEE1_TAddress)0x100000,&mydata);

I attached my demo code and video, it's for 9S12XHY256 but the method is the same for all HCS12X device

Have a great day,
Zhang Jun
