there is an 8ms cycle, and the motor is on for a part of that:
1ms for power level 0, 2ms for power level 1, up to all the 8ms
for power level 7. The rest of the time the motor is floating,
i.e. the motor inputs are disconnected, not shorted.
Like this (you need a fixed width font for this to come out nicely):
