FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Table 21. High-Side Out (HSOUT) Drivers Truth Table (Motor Driver Configured for H-bridge DC Motor)
Note: The HSOUT terminals are controlled by the OUT1 and OUT2 signals (Bit 14 and Bit 15 in the NORMAL input frame).
HSOUT is only available when DC motor is configured as Motor Driver C. (Set Bit 4 = 0 in CONFIG frame.)

Notes
33. To reduce parasitic dissipation associated with the body diode, the counterphase is turned on for synchronous rectification.
34. The current limit sense function may be disabled when the outputs are disabled. Hence, the output will oscillate between the requested
state from the Truth Table and this state.
