9description:
10  The Microchip PIC32 family of microcontrollers (MCUs) includes models with
11  Secure Digital Host Controller Interface (SDHCI) controllers, allowing them
12  to interface with Secure Digital (SD) cards. This interface is used for reading,
13  writing, and managing data on SD cards, enabling storage and data transfer
14  capabilities in embedded systems.
