3.4.7. TX Promiscuous (Transparent) Mode

In transmit path promiscuous mode, the client frame bytes are passed on without modification for the MAC to do encapsulation.

It can be achieved by setting various register fields below:

  • Disable Source Address Override
  • Disable CRC insertion
  • Disable Pad Insertion
  • START, PREAMBLE, SFD, EFD, and IDLE characters are always added by the MAC during encapsulation process.

The client must still guarantee that the minimum number of bytes provided meets the MAC requirements.
