What's the link with microSD card here ?

Sorry, what's the link with the PWM build-in, and your case ?
This comment is linked to the comment in the datasheet:
""
If GPIOC is not work as SDIO port, please do not pull CARD_DET(GPIOC_6) low when system booting
up, to avoid romcode trying to boot from SD CARD.
""
Seems pretty explicit for me.
