Bits 9:0 – RXSE[9:0] Receive Symbol Errors

This register 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 bit 8 is set in the Network Configuration Register, 10240 bytes if bit 3 is set in the Network Configuration Register). If the frame is larger it will be recorded as a jabber error. See GMAC Network Configuration Register.
