   confirmed that there are two index tracks, one at track -2 (relative to user data starting on track 0) and another on track 616 (user data ending on track 614). the D2 square wave is directly from the hall effect sensor, 2 cycles per revolution. the D1 pulses are this signal divided by 2. MCU read data is the index signal as seen by the MCU after being processed with a one-shot.
