For the curious, here is how the values above were computed:



 * slowest measurable speed: clock/(255*divider)

 * accuracy around 3000 RPM: 3000^2/clock

 * highest accurate speed: sqrt(clock*100)



The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100

RPM as the lowest acceptable accuracy.
