Part Number:DRV8711

Hello!

I am using DRV8711 in direct PWM mode. I input signals in accordance with "Table 2. Direct PWM Input Mode Logic" page 12 Datasheet. As you can see on the diagram, the AIN1 signal is constantly kept at a high level, and the AIN2 signal is at 50% PWM. According to the table number 2 datasheet I expect to see on channel A1HS - 50% of PWM 0 - 34 volts, and on channel A1LS a constant voltage of 10 volts supporting the low side is constantly open. But in fact I see that high and low sides are completely closed at the beginning of each period of PWM. You can see it on the diagram. Explain what could be the reason, please.
