EEL_Open

[Function]

EEPROM emulation preparation processing

This function makes the EEPROM emulation executable.

[Format]

void

__far EEL_Open(void)

CALL !EEL_Open or CALL !!EEL_Open

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

[Pre-conditions]

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

2. If EEPROM emulation was executed, the processing up to EEL_Close and FDL_Close function must be

executed to stop the EEPROM Emulation processing.

[Post-conditions]

None

[Cautions]

After the EEL_Open function is executed and the EEPROM emulation has been transitioned to the opened state,

the FSL cannot be executed. In addition, STOP mode and HALT mode cannot be executed. To execute the FSL,

STOP mode, or HALT mode, execute the EEL_Close and FDL_Close functions to transition the EEPROM

emulation to the uninitialized state.

[Register status after calling this function]

No registers are corrupted.

[Arguments]

None

[Return values]

None
