The Disable 4-byte Mode command is executed to exit the 4-byte address mode and return to the default 3-byte
address mode. After sending the Disable 4-byte Mode command, the EN4B bit (S11) will be clear to be 0 to
indicate the 4-byte address mode has been disabled, and then the address length will return to 24-bit.
