Just another question:

Using SDCC I made something like this:

unsigned int mainoff = 5000;
mainoff = ~(--mainoff);
_asm
	mov    _TL2,_mainoff 
	mov    _TH2,(_mainoff + 1)   
_endasm;

Its suppose to set TL2 and TH2 to Two's complement mainoff so it will take mainoff ticks to overflow. Is this correct?


P.S: In the program mainoff is limited to: 1-50,000

Thanks.
