Register Write
• Click button ‘W’ at the right end of a register to write this register to the LM10500.
• Click menu Operations, then select Write all (Ctrl+W), to write the current values in the GUI to all
registers in the LM10500.
• Click menu Settings, then select Update immediately, when checked, registers in LM10500 are written
whenever the buttons in the GUI are updated.
• Click menu Operations, then select Direct access, to write to a register by providing its address and
value, as shown in Figure 9.
