Note : The “H” state for FR is defined as a voltage of 8V or higher, and the
FR
“L” state for FR is defined as a voltage of 4V or lower.

Note : For the Hall inputs, the input high state is defined to be the state
H
where the (+) input is higher than the corresponding (-) input by
L
0.01V or higher, and the input low state is defined to be the state
H
where the (+) input is lower than the corresponding (-) input by
0.01V or higher.
