T2081 SPI pin Muxing

Question asked by Hemant Kumar Tiwari on Jun 30, 2020

Hi,

In my current design using t2081, I want to interface both SPI and eMMC card. While seeing the datasheet of t2081 i found that SPI_CS0 pin is muxed with sdhc_dat4 which i need for my eMMC interface.

 

Can anyone tell me that how I can use SPI_CS0 pin for both the cases i.e. i can use same pin for both SPI CS as well as eMMC DAT 4? Do I need some kind of external circuitry to do the same?

 

Regards

Hemant
