7.3.9 Reset to SoC (nRSTOUT)

The reset output (nRSTOUT) is an open-drain output, intended to release the reset to the SoC or FPGA at the end of the power-up sequence. The timing for nRSTOUT is configured in the sequence. nRSTOUT is driven low until the device enters ACTIVE state or when powering-down from ACTIVE- or STBY-state. The pin is driven high during ACTIVE state. In STBY-state, the pin is driven high or low depending on bit nRSTOUT_STBY_CONFIG in register STBY_2_CONFIG.
