3. It is recommended to set PB8 in a mode other than analog mode after startup to limit consumption if the pin is left

unconnected.

1. The gate driver IC is designed to support these GPIOs configuration only. Different configuration could cause device

malfunctioning. The GPIO input configuration without pull-up or pull-down is always allowed.

2. The lines are protected against conflict configuration. If the MCU GPIO is wrongly configured in push-pull mode, the device

is not damaged.
