This option is used to enable/disable CRC4 generation and checking. It is useful with some net-
works which do not support CRC4 framing but only PCM30 framing. By default, the CRC option
is ON.
Note: After changing this option, MMC 418, Card Restart, must be used to restart the card to make the
change effective.
