100Base-TX receiver-based error register that
increments when an invalid code symbol is received
including IDLE symbols. The counter is incremented
only once per packet, even when the received packet
contains more than one symbol error. The 16-bit
register counts up to 65,536 (2
if incremented beyond that value. This register is
cleared on reset, but is not cleared by reading the
register. It does not increment in 10Base-T mode.
