14.1.1 Full bridge
When in full bridge configuration, the drivers will behave according to the following truth
table:
Note: Note: When “low power mode” is active, the bridges will enter in low power state and will
reduce its biasing thus contributing to the power saving.
When a current limit event occurs this event will be latched and the bridges will remain in
high impedance state for the off time.
