How to use the Software
STK200 Starter Kit 6-5
This option programs and verifies each location from the selected buffer window into the
appropriate location in the device.
Note: It is advisable to erase the device before programming unless you are adding
extra data to existing data in the device.
If you are changing data, then you cannot change any programmed bit from a 0
to a 1 without erasing the device first. You can, however, change a bit from a 1
to a 0. For example, BB could be changed to AA but AA cannot be changed to
BB. You will not be able to program the device if the write lockbit has been set.
If this function is selected from the “Program” menu, it will only program the Pro-
gram Memory. In devices which also have EEPROM Memory available, you
must use the “Program EEPROM” command.
The “Program Device” speed button will carry out either the “Program Memory” or “Pro-
gram EEPROM” command, depending on which buffer is on top of the desktop.
6.18 Verify Device
Verify device is a programming function.
It is available on the “Program” menu, or on the “Above” button on the speed bar.
This verifies each location in the program memory buffer window with the appropriate
location in the device.
Note: This function will only verify the Program Memory. In devices which also have
EEPROM Memory available, you must use the “Verify EEPROM” command.
The “Speed” button will either verify the program or EEPROM memory, depending on
which buffer is currently selected.
6.19 Program
EEPROM
Program EEPROM is a programming function.
It is available on the “Program” menu or on the “Above” button on the speed bar. The
speed button will program the current buffer into the appropriate memory space in the
device, depending on which window is currently focused.
This programs and verifies each location, in the EEPROM memory buffer window into
the appropriate location in the device.
Note:
As the EEPROM features an auto-erase function, it does not require a chip-
erase to be performed prior to programming. A chip-erase is only required if the
lock bits are set.
The “Speed” button will either program the code or EEPROM memory, depending on
which buffer is currently selected.
6.20 Verify EEPROM
Verify EEPROM is a programming function.
It is available on the “Program” menu, or on the “Above” button on the speed bar.
This verifies each location, in the EEPROM buffer window with the appropriate location
in the device.
The EEPROM buffer must be selected (on top) if the speed button is used.
6.21 Read Device
Read Device is a programming function.
