32  * @brief Reads Nippon Denso 24/2 sensors
33  *
34  * This file contains the two interrupt service routines for handling engine
35  * position and RPM signals from mainly Toyota engines using this sensor style.
36  *
37  * One ISR handles the 24 evenly spaced teeth and the other handles the two
38  * adjacent teeth. This signal style provides enough information for wasted
39  * spark ignition and semi sequential fuel injection.
40  *
41  * Supported engines include:
42  * - 4A-GE
43  * - 7A-FE
44  * - 3S-GE
45  * - 1UZ-FE
46  * - Mazda F2T
47  *
48  * @note Pseudo code that does not compile with zero warnings and errors MUST be commented out.
