Hi Kasu,
Is this for a S12X?
Variables allocated in NO_INIT segments are not written to by the
startup code, therefore the values are
either garbage, values written into it before or some otherwise by the
hardware defined values.
For RAM and after the power on startup, I would expect them to contain
garbage.
