Voltage Monitor Circuit
The voltages '1V' and '3.3V' are monitored by the voltage monitor circuit U4, which generates the PS_POR_RST reset signal if monitored voltages have transient interruptions. The reset signal is connected to the SC CPLD U14 and forwarded to the Zynq MIO bank 500 'PS_POR' pin:
