In《Jetson_AGX_Xavier_Series_OEM_Product_Design_Guide_v2.0》document，PEX_Lx_RST_N/PEX_Lx_CLKREQ_N signals are pulled up to 3.3V，but they are 1.8V electrical level in 《JetsonAGXXavierSeriesDatasheet_DS09654001v1.1》document. Which value of electrical level is right?
Both are correct. They are 1.8V pin, but 3.3V tolerance enabled.
