Table 20. Low-Side Out (LSOUT) Drivers Truth Table (Motor Driver Configured for H-bridge DC Motor)

Note The LSOUT terminals are controlled by the OUT1 and OUT2 signals (Bit 14 and Bit 15 in the NORMAL input frame).

LSOUT is only available when Motor Driver C is configured as DC motor. (Set Bit 4 = 1 in CONFIG frame.)
