6. Limitations
===============
- Caution about compiler option -reserve_r2:
   Register r2 is not used by the OS, i.e. the OS does not use r2 as data or address register.
   However register r2 is always stored to stack and restored from stack by the OS when the context is switched.
   Therefore register r2 cannot be used like global variable to share data among tasks, ISRs or functions.
   
- Caution about compiler option -registermode=22 and -registermode=26:
   Registers r15...r24 are not used by the OS, i.e. the OS does not use r15...r24 as data or address registers.
   However registers r15...r24 are always stored to stack and restored from stack by the OS when the context is switched.
   Therefore registers r15...r24 cannot be used like global variable to share data among tasks, ISRs or functions.
