16.9.9 Operation of Flash Memory
The db33 supports flash memory on the target board and the S5U1C33104H flash memory for free-run.

(1) Loading the flash routine
(2) Setting the flash condition
The db33 comes provided with the utility and commands that write/erase the flash memory in the S1C33
chip or on the target board. They can be used in ICE (note), ICD and debug monitor mode.
Data should be written to the flash memory by the procedure shown below.
The examples in this section are extracted from "cc33\sample\dmt33004\led2.cmd".
For more information, refer to the "readme.txt" for the flash support utility fls33. ("fls33" and "readme.txt"
can be installed using "cc33\utility\fls33\fls33vXX.exe".)
Load the flash routine (erase and write routines) into a memory such as the internal RAM using the lf
command.
Example:
Actual erasing/writing will be done by this routine.
The flash routine provided by Seiko Epson uses 0x40 to 0x7ff (2KB) of the internal RAM.
Set the flash memory start and end addresses, and the entry addresses of the erase and write routines loaded
in Step (1) into the db33.
Example:
Since the S5U1C33104H is shipped with the firmware Ver. 1.x, update the ICE firmware using
the program located in the "cc33\utility\ice33v20\" directory. For the update procedure, refer to
the "readme.txt" of the updater.
The Seiko Epson routines mainly support AMD type flash memories and can be installed by
executing "cc33\utility\fls33\fls33.exe". The source and required files are included, so the routine
can be modified if necessary.
