/// Interface for configuration the Enhanced Embedded Flash Controller (EEFC)

37
/// !Usage
38
///
39
/// -# Enable/disable %flash ready interrupt sources using EFC_EnableFrdyIt() 
40
///    and EFC_DisableFrdyIt().
41
/// -# Translates the given address into which EEFC, page and offset values 
42
///    for difference density %flash memory using EFC_TranslateAddress().
43
/// -# Computes the address of a %flash access given the EFC, page and offset 
44
///    for difference density %flash memory using EFC_ComputeAddress().
45
/// -# Start the executing command with EFC_StartCommand()
46
/// -# Retrieve the current status of the EFC using EFC_GetStatus().
47
/// -# Retrieve the result of the last executed command with EFC_GetResult().
