When LP5814, LP5816 or LP5817 is chosen on the Start Page, after clicking the EXPLORE button, the GUI jumps to the Home Page.

When LP5815 or LP5814I is chosen on the Start Page, after clicking the EXPLORE button, the instant blinking disable prompt window appears as shown in Figure 3-6.

  • Click YES to set the INSTABLINK_DIS bit as 1.
  • Click NO to keep the INSTABLINK_DIS bit as 0.

As for the LP5815, the STAT is shorted to the GND by default through the jumper J3. The instant blinking function is disabled even though the INSTABLINK_DIS bit is 0. To have the instant blinking on the OUT0, remove jumper J3.

Either click Yes or No so the GUI jumps to Home Page.
