Some pin voltage confused？

Hi NV team，

from 《Jetson_Orin_NX_Orin_Nano_Pin_Descriptions.xlsx》：
1）pin177（HDMI_CEC）：Usage/Description column says 10kΩ pull-up to 1.8V on the module， but in schematic《P3768_A04》， HDMI_CEC 162Kohm_1% PU to VDD_3V3_HDMI, which one is right？

2）pin250（SLEEP/WAKE*），Usage/Description column says100kΩ pull-up to 1.8V on the module. but pin type column says CMOS-5V and in schematic 《P3768_A04》SLEEP/WAKE*=PWR_BTN* which is 10Kohm pull up to VDD_5V_SYS，which one is right？

Please help clarify here， thanks！

  1. HDMI_CEC pin is 1.8V OD pin (3.3V tolerant), the pull-up on module is not mounted.
  2. Both are correct. SLEEP pin is pulled up to 5V on carrier and routed to a SoC pin on module through a diode and then pulled up to 1.8V.

Roger that， thanks!
