4.4.12 LED signaling

LED signaling is enabled by switches SW8/SW9 and jumper J27. The LED signaling can be turned OFF
manually at any time to avoid undesired losses and obtain more accurate current consumption measurements.
LED signaling displays the state of the following signals:
• Signals: RSTB, FS0B, INTB, LIMP0; MCU status pin (to be used during software development for debugging
purposes)
• Power: HVBUCK regulator output, HVLDOx regulator outputs
• Power supply: VBAT, MCU supply
• OTP control: Debug 5 V, OTP 8 V
