摘　　要：定量测试8XC196KB系统定时器2的精确计数与定时性能,实验结果表明:激活快速计数功能与关闭此项功能相比,可将定时器2的计数与定时精度提高8倍,最高有效计数频率为系统晶振频率的1/4.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.
