TI recommends using VMON_VSYS for early supply failure indication. When not used, connect VMON_VSYS, VMON_3P3_SOC and VMON_3P3_MCU pins to VSS through separate 0 Ω resistors and add test point for future expansion.
It is recommended to connect the VMON_1P8_SOC and VMON_1P8_MCU pins to respective supplies. Grounding these signals would short internal 1.8 V supplies and is not allowed.
