Note: “H” for FR means a voltage of 2.50V or above. “L” for FR means a voltage of 0.4V or below.  
(Vcc1 = 3V)  
Note: At the Hall input, “H” means that the potential of the (+) terminal for each phase input is at least 0.02V higher than the (–) terminal.  
“L” means that the potential of the (+) terminal for each phase input is at least 0.02V lower than the (–) terminal.
