CHAPTER 8: DEBUGGER
S5U1C63000A MANUAL EPSON 213
(S1C63 FAMILY ASSEMBLER PACKAGE)
efl (erase flash memory)
Function
This command erases the contents of the ICE flash memory (including map information) and removes
its protect function.
Format
efl↵ (direct input mode)
Example
>efl↵
Clear flash memory ... done!
>
Note
When erased by the efl command, all data in the flash memory is initialized at 0xff. Even when part of
the data, such as a program, is thereafter written to the flash memory by the slf command, all other
data remains unchanged (= 0xff). In this condition, the ICE cannot be operated in free-run mode. In
order for the ICE to be operated in free-run mode, always make sure that after erasing the flash
memory, all the data has been written into the flash memory.
In the ICE, furthermore, the default values for all option data are 0x00. Consequently, if you write to
the flash memory before loading option data (lo command), the data you have written to the flash
memory is overwritten by 0x00.

[File | Flash Memory Operation…] menu item

memory" from the [Operation] list box and then
