BGO（Back Ground Operation）function

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

program. This allows the user program to run during the data flash operation and so is called back ground operation

(BGO).

The data flash read or write command processing is started by executing the EEL_Execute function, and the

processing is continued and completed by executing the EEL_Handler function. For this reason, the EEL_Handler

function must be executed continuously until the processing is completed.

To see if the processing requested from the EEL_Execute function has been successfully completed, call the

EEL_Handler function from the user program and check the status of ongoing processing.

The EEL_CMD_SHUTDOWN command does not require calling of the EEL_Handler function. However, we

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