This method must be applied to Ethernet configuration registers (including those relate to unused
module features). Detailed information on the implementation of this method can be found in

Protocol error signals including hardware CRC
ST
Ethernet communication module embeds protocol error checks (like overrun, underrun, timeout,
packet composition violation etc.) and CRC-packet checks as well, conceived to detect network-
related abnormal conditions. These mechanisms are able anyway to detect a percentage of
hardware random failures affecting the module itself.
Error flag raise and optional Interrupt Event generation
