3.12 Uploading a Device's Contents Into PC Memory± the Upload Command

When you use the upload command, the microcontroller and gang program- mers display different prompts and messages. The microcontroller program- mer is discussed in sub-section 3.12.1, and the gang programmer is discussd in sub-section 3.12.2.

3.12.1 Uploading Using the Microcontroller Programmer

Use the upload command to upload the device contents to the PC memory . Starting the upload is a simple one-step process of defining PC memory and device address ranges.

Step 1: 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.

For example, the valid address ranges defined for the TMS370C756 device are (1E00h±1FFFh) and (4000h±7FFFh). When the default is used, the contents of the device inside (1E00h±1FFFh) and (4000h±7FFFh) are read and uploaded to PC memory starting at ad- dress 1E00h and 4000h, respectively.

However, if you want to upload device contents from a range in the device other than the default, enter the start address of the range and then the 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 at the following prompt.

PC memory base address:

The default for this prompt is the value entered for the device base address prompt. If you want to upload to a different PC memory loca- tion, enter the address.

Once the actual uploading begins, it proceeds packet by packet in180-byte segments. Before a packet is uploaded, the programmer verifies that the source device address is inside the valid address ranges defined for the cur- rent device type. If the address is not inside the range, the following error mes- sage is displayed:

Address Out of Range, Press any key

Press any key to erase the error message and return to the display command menu.
