8 * - The period is fixed to 1 ms and is generated continuously despite changes
10 * - Changes to the duty cycle or enable/disable state take effect immediately
12 * - The device cannot generate a 0% duty cycle. For duty cycles below 1 / 256
13 * ms, the output is disabled and relies upon an external pull-down resistor
