Commands
Load Device
Load Logic Device
Load Memory Device
The Load Device command allows you to copy data from a master device into
RAM. Depending on whether you select a logic or memory device, either the
Load Logic Device screen or the Load Memory Device screen will appear when
you select this command.
Main Menu / Load Device / Load Logic Parameters screen
To load user memory with data from a logic device, follow these steps:
1. Select and socket a logic device.
2. Select Load Device from the Main Menu. The Load Logic Device screen is
displayed.
3. Press ENTER to begin the loading.
4. When the load operation is complete, the programmer displays the
following message: OPERATION COMPLETE: Sumcheck = xxxx.
Main Menu / Load Device / Load Memory Parameters screen
To load user memory with data from a memory device, follow these steps:
1. Select and socket a memory device.
2. Select Load Device from the Main Menu.
3. From the Load Memory Device screen, specify the parameters you want,
then press ENTER to begin loading.
4. When the load operation is complete, the programmer displays
OPERATION COMPLETE: Sumcheck = xxxxxxxx
You can specify the following parameters in the Load Memory Device screen:
� Data Word Width
Sets the word width of data to be loaded. For 8-bit or larger devices, the
minimum word width equals the device width and the maximum word
width is 64. For 4-bit devices, the word width choices are 4, 8, 16, and 32.
This value should match the data bus word width in the target system for
the device being programmed. The default value is the device word width.
� Next Device
Designates the next device (next set member) in the set. For example, if
you are using 8-bit devices and have specified a word width of 16 bits on
the Load Memory Device screen, it requires two devices to store each 16bit
word.
Type 1 for the next set member to direct the programmer to load the first
device in the set at even-address bytes of the memory block.
Type 2 to direct the programmer to load the second device at odd address
bytes of the memory block.
