I am working on a design with a processor which has I2C SCL line & SDHC_CD(Card Detect) pins multiplexed. I need to use I2C line. I am giving SD Card for boot code of processor. I have below doubts :-
- Is it mandatory to connect Card Detect pin to the Host?
- If I dont use SDHC_CD, Will the Processor be able to read from SD Card?
- If I need to use CD pin, Is there any way to use both functionalities?
Can anyone please share the link for SDHC protocol?
