Dear all,

 

We have a question about the CDPL/WPSPL field of the uSDHCx_PRES_STATE register of i.MX6UL.

 

We are going to connect WiLAN module to an SD card slot.

CD_B signal and WP signal are not used in the WiLAN module.

In this case can CD_B pin and the WP pin be used as other functions?

 

When these pins are used as other functions,
if the CDPL/WPSPL field of the uSDHCx_PRES_STATE register is read, what kind of value is it?

 

May I have advice?

 

Best Regards,
Yuuki
