Hi,
Im building an 8051 system and right now im trying to implement a Software RTC. I've calculated the timer 0 constants for my crystal frequency and still it loses about 5 seg per minute.
My question is: After the timer overflow when the TL anf TH vars starts to increment again? after the RETI in the int routine? after set TL and TH to preset values? or it just keep incrementing as if nothing happend?

thanks already!
