Bits 9:0 – RXSE[9:0] Receive Symbol
Errors
This bit field
counts the number of frames that had GRXER asserted during reception. For 10/100
mode symbol errors are counted regardless of frame length checks. For gigabit mode
the frame must satisfy slot time requirements in order to count a symbol error.
Additionally, in gigabit half duplex mode, carrier extension errors are also
recorded. Receive symbol errors will also be counted as an FCS or alignment error if
the frame is between 64 and 1518 Bytes (1536 Bytes if NCFGR.MAXFS=1). If the frame
is larger it will be recorded as a jabber error.
