| Abstract: | The strict counting and timing functions of timer2 circuit built-in 8XC196KB system are accurately measured. The measured results showed that to compare enable quickly counting function with disable this function, it can increase 8 times counting and timing accuracy of timer2 circuit; maximum valid counting frequency is quarter of system oscillator frequency. |
