Read Device
Selecting Load XData HEX File from the HexData menu causes the target device to be
read by the OCD hardware. When the host PC detects two or more hardware devices, it
prompts the user to select which device to read, as indicated in Figure 81.
If the selected target device is unlocked, the OCD hardware will read the code, XData and
configuration values, then update the display and the checksum.
If the selected target device is locked, the OCD hardware will display the term LOCK and
prompt the user to read the configuration only.
Most Recent Files
As the user opens and closes files, these files will appear in the Hex Data menu, and can be
selected at any time in a current or future session. The maximum number of most recently-
used files that will appear in the Hex Data menu is eight. See the example in Figure 82,
which shows that the user has recently opened only three files; the third file (selected in
the figure) is the demo.hex file.
