Default CodeLoader Modes for Evaluation Boards
CodeLoader saves the state of the selected LMK04816B device when exiting the software. To
ensure a common starting point, the following modes listed in Table 3 may be restored by
clicking “Mode” and selecting the appropriate device configuration, as shown in Figure 2 in the
case of the LMK04816 device. Similar default modes are available for each LMK04816B
device in CodeLoader. Choose a mode with CLKin0 for differential clock signal or CLKin1 for a
single ended signal.

After restoring a default mode, press Ctrl+L to program the device. The default modes also
disable certain outputs, so make sure to enable the output under test to make measurements.
