Chapter 3 EEL Functional Specifications

This chapter describes the functional specifications of the EEL required for the user to execute EEPROM

emulation.

3.1

EEL Functions / Commands of the EEL_Execute Function

The table below summarizes the EEL functions offered by the EEL.

Table 3-1

EEL Functions

EEL function name

Functional overview

FDL_Init

Initializes the FDL.

FDL_Open

Preparation processing of FDL

FDL_Close

End processing of FDL

EEL_Init

Initializes the EEL

EEL_Open

Preparation processing of EEL

EEL_Close

End processing of EEL

EEL_Execute

Manipulates data flash with commands.

Command : EEL_CMD_STARTUP

EEL_CMD_WRITE

EEL_CMD_READ

EEL_CMD_REFRESH

EEL_CMD_VERIFY

EEL_CMD_FORMAT

EEL_CMD_SHUTDOWN

EEL_Handler

Controls the EEL while it is running.

EEL_GetSpace

Checks free space in the EEL block

EEL_GetVersionString

Obtains EEL version information.

With the EEL_Execute function, the following commands can be executed.

3. 1. 1

EEL_CMD_STARTUP command [Startup processing]

This checks the block status and sets the system to the EEPROM emulation start (started) state.

3. 1. 2

EEL_CMD_SHUTDOWN command [Shutdown processing]

Set the EEPROM emulation operation to the stopped state (opened).

3. 1. 3

EEL_CMD_REFRESH command [Refresh processing]

The latest stored data is copied from the active block (copy source block) to the next block (copy destination

block) in the EEL pool after the erase processing. This makes the copy destination block active.
