L9958SBTR missing VDDIO pin

Hello STM Community,

I am attempting to interface a L9958SBTR h-bridge module with a STM32F031K6 MCU. The h-bridge module claims to support 3.3v logic levels, however the VDDIO pin which determines the logic level of the SPI SO (serial data out) pin is missing on this package. I have not received the modules yet so I cannot test the logic levels with an oscilloscope. I'm assuming that all the module's input pins will work with 3.3v signals, but how can I be sure that the SPI output won't fry the MCU (I.E. is outputting 3.3v and not 5v signals)?

Thank you for your time
