Now I use the MCU MC9S12XET256,  when the MCU in the Stop or Wait Mode ,I can wake it up by a input Interrupt(PP2),Now I want to wake it up by the PIN XIRQ, which regiter or instruction I should program before it go to stop or wait mode., The datasheet say XIRQ enable by cleaer the X-BIt in CPU conditon code register,and I don't particularly understand.
