I was looking at the datasheet for the flight core and noticed that the ICM-20602 and ICM-42688 both share the PA5 pin from the STM32 microcontroller. As these chips are on different SPI buses and the PA5 pin is for the SPI1 SCK, I was unsure if the datasheet is wrong or if there is something going on beyond my knowledge. Thanks.
