This read only flag reflects the state of the L0 input
This read/write flag is set at overcurrent condition on H0
1 = L0 input high
0 = L0 input low

(HBOUT) owing to the fact that all half-bridge outputs are
switched off.
This read only flag reflects the state of the H0 input
This read/write bit enables the 2pin hall-effect sensor
This read/write bit disables the H0 Pull-up resistor.
These read/write bits select the mode of the H0 input
Outputs HB1:HB4 provide four low-resistive half-bridge
Reset clears all bits in the H-Bridge Output Register
HB1:HB4 output features
•Short circuit (overcurrent) protection on high-side and
•Current recopy feature (low-side MOSFET)
•Overtemperature protection
•Overvoltage and undervoltage protection
•Active clamp on low-side MOSFET
1 = Hallport sensed high / current below threshold
0 = Hallport sensed low / current above threshold
1 = Hallport H0 is switched on and sensed
0 = Hallport H0 disabled
