Uploading a Device's Contents Into PC Memory

During the uploading process, the programmer displays a status message on the bottom line of the screen to indicate the address currently being read.

Reading at address 7000 (hit ESC key to abort)

This message is updated when the programmer starts to upload the next pack- et.

If you want to terminate the uploading process before it has completed, press to abort the process and return to the display command menu.

3.12.2 Uploading Using the Gang Programmer

Use the upload command to upload the device contents to the PC memory.

Step 1: Identify the device you wish to upload.

Enter Device #[1...16]

Step 2: Define the address range of the device contents you are uploading.

Device base address: all

The default for the base address prompt, all, causes the valid ad- dress ranges defined for the current device type to be read and uploaded to the PC memory.

However, if you want to upload device contents from a range in the device other than the default range, enter the start address of the de- sired range and then its size at the next prompt.

Size (in bytes): 0000h

When specifying values other than the default, you must also define the PC memory base address, that the contents of the device will be loaded into, at the following prompt.

PC memory base address:

After you have entered all the parameters correctly (or simply chosen all at the PC memory base address prompt), the gang programmer conducts a device test. If the device specified fails (or that socket is empty), the programmer beeps and turns on the LED below the failed device. Also, an error message prompts you about the device failure:

Device test failed, continue? (y/n)

At this time, you should try to re-insert the failed device and start uploading its contents again.

It is possible that a defective deviceÐa device with bent pins or a device that has been incorrectly insertedÐwill affect all of the devices on the Gang pro- grammer. If this is the case, the following error message is displayed:
