ALE
• ALE: Alignment Errors
An 8-bit register counting frames that are not an integral number of bytes long and have bad CRC when their length is truncated
to an integral number of bytes and are between 64 and 1518 bytes in length (1536 if bit 8 set in network configuration register).
This register is also incremented if a symbol error is detected and the frame is of valid length and does not have an integral num-
ber of bytes.

A 16-bit register counting the number of frames experiencing deferral due to carrier sense being active on their first attempt at
transmission. Frames involved in any collision are not counted nor are frames that experienced a transmit underrun.
