* \section Purpose
*
* Interface for configuration the Enhanced Embedded Flash Controller (EEFC)
* peripheral.
*
* \section Usage
*
* -# Enable/disable %flash ready interrupt sources using EFC_EnableFrdyIt()
* and EFC_DisableFrdyIt().
* -# Translates the given address into which EEFC, page and offset values
* for difference density %flash memory using EFC_TranslateAddress().
* -# Computes the address of a %flash access given the EFC, page and offset
* for difference density %flash memory using EFC_ComputeAddress().
* -# Start the executing command with EFC_PerformCommand()
* -# Retrieve the current status of the EFC using EFC_GetStatus().
* -# Retrieve the result of the last executed command with EFC_GetResult().
