[bit9:0] count: Receive symbol errors
A 10-bit register counting the number of frames that had
RX_ER
asserted during reception. For 10/100
MBit/s mode symbol errors are counted regardless of frame length checks. 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.
