6.4 SD/MMC interface
This paragraph describes the card reader JEDED/MMC standard version 5.0 compliant.
The filter used is EMIF06-MSD02N16 by ST.
The SD/MMC card reader needs to use a power switch to limits the output current to a safe level in case the
output load exceeds the current limits threshold or a short is present.
Use an STMPS2151MTR by ST.
The figure below shows SD/MMC card reader diagram.
