|
|
* \par Purpose
|
|
*
|
|
* Interface for configuration the Enhanced Embedded Flash Controller (EEFC) peripheral.
|
|
*
|
|
* \par 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_StartCommand()
|
|
* -# Retrieve the current status of the EFC using EFC_GetStatus().
|
|
* -# Retrieve the result of the last executed command with EFC_GetResult().
