SERIAL DOWNLOADER FLASH PROTECTION
Configure the flash protection by using the ADE71xx/ADE75xx
serial downloader interface. Clicking the
Flash Protection
button on the serial downloader panel brings up the window
shown in Figure 34. Configure the protection after downloading
the required hexadecimal file to the flash memory but prior to
pressing the RESET
From this window, the write/erase and read protection can be
set up for each of the 31 pages of flash. Changes made to the
flash protection should be written to the part using the
WRITE
command. Note that when the
WRITE
button is clicked, the
flash memory is directly modified and, therefore, once a page
has been locked (that is, 0x00 written to the flash location) it
cannot be unlocked (that is, restored to 0xFF) without resetting
the part. To activate the protection, reset the ADE71xx/ADE75xx
by pressing the
button, S3, to begin code execution.
RESET

push-button, S3. Note that for best
practice, do not enable the read or write/erase protection while
debugging or emulating code. A full description of the flash
protection scheme can be found in the respective data sheet.
