Detailed Description

Contains API prototypes for the NVMCTRL (Nonvolatile Memory Controller) driver.

These APIs provide direct register access and have no functional knowledge of the register interface. No input or output validation is performed in the drivers. It is the responsibility of the calling function to use them correctly according to the register interface specification.
