I have a problem with HCS12x microcontrollers.
Xgate code either run from RAM or the FLASH ( RAM is more preferrable as x gate runs only at half the speed of CPU ).
i came to know that at the startup.c, x gate code is copied from 'flash' to 'ram'.
Inorder to trace this two project files
1. with xgate in flash
2.with xgate in ram
I compared both the files i.e startup.c and datapage.c for both x gate in ram and x gate in flash . There is no single difference between the two....
i'm confused!!!.... howz the demarcation done between x gate in flash - > x gate ram in startup.c
help me out
