* Notes: In order to eliminate warning messages L1912 "Object xxx overlaps
* with another", you can replace LIN_Reg definition
* extern volatile LIN_REGTYPE LIN_Reg;
* by: #define LIN_Reg (*(volatile LIN_REGTYPE*)0x1000) in regs.h file
* and delete this declaration in lininit.c file.
* Alternatively, you can disable this message.
* Note that for the first mentioned approach, debug information
* for variables are not generated and they do not longer show up
* in the map file.
