关于Example_posspeed.c的问题

   关于T法测量公式,有一点不明白的地方,请教:

6000 rpm = [32(150MHz/128)*60s/min]/[4000(t2-t1)]
 t2-t1 = [32(150MHz/128)*60 s/min]/(4000*6000rpm)          - Equation 5
 = 94 CAPCLK cycles

= maximum (t2-t1) = SpeedScaler

上述公式,基频/最大转速=6000RPM时,t2-t1(单位位置之间的时间间隔)不是应该最小么?  这里为什么SpeedScaler=maximum(t2-t1)=94 QCAPCLK???

没理解这是撒子意思?
