I am using AT89C2051 in my clock project and the process of scaning of segments is being carried out by using timer1 interrupt and initial time start from 12:00 when power up circuit but after 8:10 all the segments goes off even the power is on i think the microcontroller goes off. what's the solution anyone help me?
