    Sterling LWB with the VDDIO at 1.8V



      I'm using the Sterling LWB radio module attached to the SDIO peripheral of the STM32F7 microcontroller and running the WWD driver of the WICED SDK.

      We are using the VDDIO at 1.8V, hence the SDIO bus signals are expected to be all at 1.8V but, the SDIO lines DAT0 and DAT1 are pushed at 3.3V by the CYW4343W.

      Are there some bit to setup into the registers of the CYW4343W in order to correctly use the chipset with the VDDIO at 1.8V?
