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.
