  • ULINK-ME initializes the JTAG interface and detects the Chip ID.
  • If Use Reset at Startup is enabled, ULINK-ME performs a Reset Sequence.
  • ULINK-ME stops the device.
  • If Project — Options — Debug — Load Application at Startup is enabled, ULINK-ME downloads the code to the target and performs a Reset Sequence.
  • If the Project — Options — Debug — Initialization File text box contains the name of an initialization script, the debug commands in this script file are processed.
