Does the DA1469x support changing the GPIO voltage level? If so, is it possible to set different voltage levels on different pins e.g. we would like to have one SPI bus working on 1.8V (which I see is already done for reading instructions from 1.8V flash) but another SPI bus on 3.0V, to avoid using voltage level translators when communicating with one of our sensors, which only works with higher voltage levels 2.8-3.6V.
At the same time the I2C bus would have pull-ups on 1.8V, but that shouldn't be a problem even when GPIOs level is set to be 3.0V it seems..
