An internal power-on-reset (POR) circuit keeps the I/Os in a high-impedance state during power up. External supply voltage supervisors (SVS) can be used to monitor the voltage on the 3.3-V and 1.2-V rails and drive XRS low when supplies are outside operational specifications.
If the supply voltage is held near the POR threshold, then the device may drive periodic resets onto the XRS pin.
