Part Number: TM4C129DNCPDT

In TM4C129DNCPDT Data Sheet, Ethernet Controller module, MII Interface Signals, EN0TXER signal is allocated to PN6 (port N bit 6).

But TM4C129DNCPDT port N has only bit 0 to 5 as pin out.

There is an other signal allocated for EN0TXER? Or?

Thank you 

  • Hi,
    In this package (PDT) the EN0TXER is unavailable. This signal is only available in the BGA package variant. In the package that does not have the TX_ER signal, the MAC will provide a corrupt packet so that the downstream device will discard the packet. Therefore, the connected phy will not need the TX_ER input.
