TM4C1294NCPDT: TIVA datasheet Ethernet pinout - not consistant with 802.3af

Lawrence M
Prodigy 100 points
Part Number: TM4C1294NCPDT

I note in the datasheet (and eval schematic) that the RJ45 pin1 and pin2 are TX, whereas the standard has these as RX:

"Tiva™ TM4C1294NCPDT Microcontroller"  - "Figure 20-13. Interface to Ethernet Jack"

"https://en.wikipedia.org/wiki/Power_over_Ethernet" - "Pinouts"

So:

  • What is the reason for this inconsistency?
  • Will the fact that the TIVA offers “MDI/MDI-X cross-over support” resolve this issue?
