EP93xx User’s Guide
In the receiver, the MAC detects the preamble and locks onto the embedded clock. The MAC
performs destination address filtering (individual, group, broadcast, promiscuous) on the DA.
The MAC engine computes the correct FCS, and reports if the received FCS is “good” or
“bad”. The data after the SFD and before the FCS is supplied to the host as the received
data. The received FCS may also be passed to the host by setting RXCtl.BCRC.
