Discrepancy about GPIO1[5] & GPIO1[15] of P1022

[cagataykaleliog]

Hello,

There is a discrepancy about GPIO1[5] and GPIO1[15] of P1022 between its application note AN4343 and its datasheet and reference manual.

Datasheet and Reference Manual: The pin TSEC2_TX_CLK/USB2_CLK/TSEC2_GTX_CLK (Package pin number: AC26) is GPIO1_5:

Application Note (AN4343):  The pin TSEC2_TX_CLK/USB2_CLK/TSEC2_GTX_CLK is GPIO1_[15]:

Reference Manual again: The pins TSEC_1588_CLK_OUT and TSEC2_TX_CLK/USB2_CLK/TSEC2_GTX_CLK are both shown as GPIO1[15] in the figure of signal groupings:

But, the pin  TSEC_1588_CLK_OUT's alternate function is given as GPO1[15] two pages after the figure:

My guess is:

TSEC2_TX_CLK/USB2_CLK/TSEC2_GTX_CLK -> GPIO1[5]

TSEC_1588_CLK_OUT -> GPO1[15]

Could you confirm?

As per my personal understanding, in this case you should trust to datasheet.

I will report both these documentation issues to our documentation team and let you know the result.

Have a great day,

Thank you. I'll consider datasheet is right.

You, too, have a great day.

I've got a confirmation, P1022 datasheet is correct.

The correct muxing on Pin# AC26 is

GPIO1_5/TSEC2_GTX_CLK/SEC2_TX_CLK/USB2_CLK.

Figure 3-1 in P1022-RM and Table 25 in P1022 design checklist - will be corrected in the next document revision.

Thank you for for pointing.
