E8 SDCARD_D0 GP131_SDMMC_A0 SD Card (or SDIO) Data 0 Bidir CMOS – 3.3V/1.8V
I wonder when these CMOS-3.3V/1.8V pin output 3.3V instead of 1.8V,
can the output level be configured by registers after startup?
what’s the default level of these pins ? since they all marked as pd in the pin description sheet, are these pin 1.8V under POR?
If we connected these pins to a slave devcie with 1.8V maximum tolerant, Is there any chances that the slave will be damaged?
