Here is translation from translator:"MC9S12XS128MAL chip power-off place I use for some time, after almost a few hours, and then power on the chip will not start, does not work; immediately turn off the power switch, and then turn on the power switch, the power will be able to start the second chip. I do not know why. SCM now use the Flash storage."
If you are not satisfied with auto translation I would like to ask you to fix it.
