Question, i.MX6SX unused pin handling

[Aemj]

Dear team,

I would like to ask about the recommended connections for unused analog interfaces of i.MX6SoloX.

In i.MX6SX datasheet(IMX6SXCEC Rev.1), it is described in Table-5 that the recommended connection of unused VADC_IN[0:3] is float.

But in i.MX6SX hardware design guide(IMX6SXHDG, Rev.1), the recommended connection for unused VADC_IN[0:3] is said as connect to GND, in table-2-17.

Which is the truth?

I found difference on the recommended connections for unused VDD_AFE_1P2 and VDDA_AFE_3P3 as well between datasheet and hardware design guide.

Please show me which is correct about VDD_AFE_1P2 and VDDA_AFE_3P3 as well.

Thanks,

Miyamoto

Here I attached a screenshot of Table 2-17 Recommended connections for unused analog interfaces of Hardware Development Guide for i.MX 6SoloX Application Processors Rev. 1, 03/2016.

Here you see float is recommended. Perhaps you were reading an outdated Hardware Development Guide.

Have a great day,
