The Voltage of the PEX_L0_CLKREQ_N is 1.8v or 3.3v?

There is some conflicttion about the description of the Pcie Control signal like PEX_L0_CLKREQ_N.etc
In the OEM design guide Page 26 ,the signal is CMOS 1.8V,but in page 36,the signal is pulled up to VDDIO_AO_3V3?which page is right?

It’s 3.3V.

3Q,HaHa!
