  32  * @brief For evenly spaced teeth on the camshaft with a single second input.
  33  *
  34  * This is suitable for engines such as the Yamaha R1 with 8 teeth on the crank
  35  * and equally for something with 16 on the cam. Sync is provided by the second
  36  * input allowing a sequential and/or COP/CNP setup to be used.
