Note: The “H” entries in the FRC column indicate a voltage of 2.50 V or higher, and the “L” entries indicate a voltage of 0.4 V or lower. (When VCC1 is 3 V.)
At the Hall inputs, for each phase a high-level input is the state where the (+) input is 0.02 V or higher than the (–) input. Similarly, a low-level input is
the state where the (+) input is 0.02 V or lower than the (–) input.
