Hello All,

How to synchronise the Tx and Rx signals for the ETHMAC_LATEST project which uses a WISHBONE interface?? I have two state machines for Tx and Rx. when the Tx is activated alone it transmission works but as soon as RECEN bit in the MODER register is asserted high nothing works. The module is full duplex so why when setting RECEN and TXEN at the same time looks invalid ?
What is the correct behaviour ??

When we have something to send .... setup the TX_BD and TXEN=1
Return to initial idle state
*** At this point should we wait until the frame is sent before being ready for reception ?
is something received using an interrupt ?
Yes, read it and reset the current RX_BD
No, stay at idle state.

Anyone can help ?
