Why CSI Des output would damage the chip permanently?

As decribed in Camera SIPL Receive-Only Mode

The NVCSI pad on the receiving Tegra must be enabled when the deserializer drives CSI output to the lanes. Otherwise, permanent damage to the chip is possible

Then what’s the exact reason of damage?
And which chip would be damaged by CSI output? Tegra or Des? or Both?


Xavier had such a limitation; CSI pad (VDD_CSI) needs to be powered on first prior to the deserializer.
For Orin, the issue has been fixed hence there is no such permanent chip damage. Thanks.
