SAVE
The
SAVE
button gives the user the ability to save the current state of the GUI memory
array. The GUI memory array can be saved as either a HEX (.hex) file or TEXT (.txt)
file based on the user preference. Once a file type is selected, a file explorer will pop
up prompting the user to specify the file directory and name of the file.

PROGRAM
The Program feature can be used to write to the Serial EEPROM memory array,
Security register, lock Zone 0 to Zone 3, and lock the Security register. When the
PROGRAM
button is pressed, the current internal GUI buffer will be written to the Serial
EEPROM memory. The Program feature must be used when a cell is updated
(
yellow
shaded), or when a file (.hex or .txt) is loaded. If the Program feature is not
used, the data in the internal GUI buffer will not be written to the Serial EEPROM.
The Program feature can also be used to lock the four memory zones and/or the
Security register. Each zone and the Security register can be locked independently of
each other by placing a check mark in the corresponding box.
When the Program feature is used to program the Serial EEPROM memory array or
Security register, that entire memory region will be written with the current data in the
internal GUI buffer rather than only the changed values. If a specific data byte or bytes
are to be programmed, it is recommended to use the Write feature
(see
for additional information).
Note:
When using the Save feature, the software will create the data for the saved
file based on the internal GUI buffer and not on the actual data from the
Serial EEPROM.
Note:
By default, the memory array is selected. Therefore, if the user only wants
to write the Security register or lock a zone or register, the user must
unselect the memory array and select the particular operation to be
performed.
