title: Microchip PIC32 SDHI Controller

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