| 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. |
