EEL_Handler

[Function]

Continuous EEPROM emulation execution processing

This function continues executing the EEPROM emulation processing specified for the EEL_Execute function.

[Format]

void __far EEL_Handler(void);

CALL !EEL_Handler or CALL !!EEL_Handler

Remark Call this function by using ! if placing the EEL at 00000H to 0FFFFH or by using !! if not.

[Pre-conditions]

The FDL_Init, FDL_Open, and EEL_Init,EEL_Open functions must have finished normally.

The EEL_Execute function should execute

Note, and status_enu of the request structure (eel_request_t)

should be EEL_BUSY.

Note: Execution of the EEL_CMD_SHUTDOWN command does not need execution of the EEL_Handler function.

However, we recommend that you follow the command operation flowchart shown in figure 3-3.

[Post-conditions]

While status_enu of the request structure (eel_request_t) is EEL_BUSY, execute this function repeatedly. If the

EEL_Handler function is executed while no command is executed, status_enu of of the request structure

(eel_request_t) is not updated.

[Cautions]

The command execution status of the EEL_Handler function is set for the ”eel_request_t* request” used as an

argument of the EEL_Execute function. Therefore, when using the EEL_Handler function, do not free the

“eel_request_t* request” variable. For the execution state of the command specified by the EEL_Handler function,

see the list of the EEL_Execute/EEL_Handler command execution state (eel_status_t)

[Register status after calling this function]

No registers are corrupted.

[Arguments]

None

[Return values]

None
