hello everyone,
i'm using avr gcc 3.4.3
and i have specified one global variable 'dummy' as
register unsigned char  dummy asm ("r5");
this means that register r5 will be used only when variable 'dummy' gets modified..
but in my program this register is getting pushed in some other function.. and because of thet output value is getting corrupted...
is there any way to limit the use of register that we declared using above syntax..
