SDHC (SD Host Controller)
HAL API Reference » Implementation Specific

The PDL has the following weak functions to support the use of dedicated pins for card detect, write protect, pwr en, and io select signals.

If the user would like to use non-dedicated pins for these items, see the PDL documentation for how to implement these functions for use with GPIO.

- Cy_SD_Host_IsCardConnected
- Cy_SD_Host_IsWpSet
- Cy_SD_Host_EnableCardVoltage
- Cy_SD_Host_DisableCardVoltage
- Cy_SD_Host_ChangeIoVoltage

By default, if the timeout_ms parameter given to mtb_hal_sdhc_erase function is 0. The SDHC HAL driver will check to see if the connected card is emmc. If so, the timeout_ms parameter will be set to 100 milliseconds, otherwise it will be set to 1000 milliseconds.
