According to the latter, the SAI1_MCLK pad can be configured as ENET1_TX_CLK and GPR1 Bit 13 should control the direction of the pin, but I could not get any signal out of this pad. Furthermore the GPR1 description for this bit has a note: SOI bit for the pad(iomuxc_sw_input...

must set the bit “DAISY” of the OMUXC_ENET1_IPG_CLK_RMII_SELECT_INPUT register in 0 to select "Selecting ALT4 mode of pad GPIO1_IO05 for ENET1_REF_CLK1". Is it correct? May be I need to set the bit “DAISY” additionally? My main question is: Can be the pin GPIO1_IO05...
The table has REF_CLK high to TXD[1:0] valid for #1, but #1 is drawn from REF_CLK high to TXD[1:0] middle of transition. I think that regardless of which is true, my assertion is still correct, but the scale of my assertion changes. 2ns - tr(TXD) is pessimistic because tr(...
