+/// \unit
+///
+/// !Purpose
+///
+/// Interface for configuration the Embedded Flash Controller (EFC) peripheral.
+///
+/// !Usage
+///
+/// -# Initialize system master clock of the EFC with EFC_SetMasterClock().
+/// -# Enable/disable interrupt sources using EFC_EnableIt() and EFC_DisableIt().
+/// -# Enables or disable the "Erase before programming" feature using 
+///    EFC_SetEraseBeforeProgramming().
+/// -# Translates the given address into which EFC, 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_StartCommand()
+/// -# Retrieve the current status of the EFC using EFC_GetStatus().
