    programming 8051 timer

    Xtal=11.0592MHz,time delay of 5ms(milliseconds).solution 11.0592MHz/12 ,the counter counts up every 1.085us.clocks= 5ms/1.085us =4608 clocks,TL and TH the value 65536-4608 =60928=EE00H.TH=EE.Assuming I want time delay of 360 seconds how can I calculate it using this formula
