Note

⁽¹⁾ The DLYB is implemented as a core driver (not user driver), then the required user DLYB APIs are provided to the user by HAL XSPI, HAL MMC, HAL SD, HAL SDIO driver(s).

Note

⁽³⁾ The SoC services:

• The LL SYSTEM driver provides a set of APIs to retrieve the device ID and the device package type.

• The LL UTILS driver provides a set of generic APIs used for timing functions.
