Description: 1. The realization of a second timing. Set a timer interrupt every 100us, in the interrupt service routine, the number of interruptions to count, count 10000 times is 1 seconds. 2. Minutes and seconds are displayed using four digital tube 373 with the latch function of the chip can be a complete display minutes and seconds information. 373 chip-chip election would require 138 of the decoding chip and 04 chips from the anti-. 3. Tune realize single-chip computer at the time of the external interrupt and three buttons, we can realize a convenient function when transferred. For example, three button switches interrupt generated information can be used for
