Answer
After data is written to the program cache memory (SRAM), it is automatically transferred to the program memory (flash ROM). Therefore, additional online change cannot be performed while transferring the data.
Wait until the data is transferred to the program memory.
An option is available to determine whether the program cache memory should be transferred to the program memory after the completion of online change.
If the option is set not to transfer, a dialog will appear to ask whether the transfer to the program memory should be performed after the completion of online change.
