EEL_Execute

[Function]

EEPROM emulation execution function

Each type of processing for performing EEPROM emulation operations is specified for this function as an

argument in the command format, and the processing is executed.

[Format]

void __far EEL_Execute(__near eel_request_t* request_pstr);

CALL !EEL_Execute or CALL !!EEL_Execute

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.

[Post-conditions]

While status_enu of the request structure (eel_request_t) is EEL_BUSY, execute the EEL_Handler function

repeatedly.

The EEL_Execute function starts command processing and then immediately returns the control to the user

program. The command processing is continued by executing the EEL_Handler function. Therefore, the

EEL_Handler function must be executed continuously until the command processing is completed.

[Cautions]

None
