DRV8718-Q1: H-bridge combination

hi expert,

my customer use DRV8718-Q1  in the BCM application, they want check any risk of their H bridge combination.

they don't use half-bridge 1, they use half-bridge 2 and 3 to be a H bridge,  half-bridge 4 and 5 to be a H bridge, half-bridge 6 and 7 to be a H bridge, and use half-bridge 8 to be a high side switch.
