Question

Usage of pin PN12

Hello Team,

 

  1. On the Development Board, pin PN12 is used to detect whether an SD card is inserted or not; however, it is also required by xspm_p2_ncs, so I don’t think we can simultaneously use XSPIM1, XSPIM2, and PN12. Is there any other pin you would recommend for the purpose of detecting an SD card? Also, I am using the mechanical switch to detect the SD card.

 

  1. In the Datasheet, SDMMC1 is specified for the SD card

 

  1. However, in the AN5967 Document, SDMMC2 is preferred for the SD card.

 

Which port, SDMMC1 OR SDMMC2, is preferred for a microSD card?

 

Thanking you
