I am doing a small project using AT89c51 (similar to 8051).
I have used T0 as a counter with external clock of 36khz.T1 is used as the timer of 10ms.For the particular external inputs at port P1,a particular valid data is to be displayed.What the problem is that every hardware resets generates different output datas even when all input conditions are kept constant.For say, data to P1 is kept at FFH and
suppose the valid output data is 2AH. With every new hardware resets,
(even when the input is fixed at FFH and all other conditions kept constant) the output changes randomly around 2AH (say 20H at some instant and 2BH at next). What could be the problem? Please somebody help me.
