Dual Input/Output Fast Read using 4 Byte Address (DIOFR4BYTE)
The Dual Input/Output Fast Read using 4 bytes address (DIOFR4BYTE) instruction is very
similar to the Dual Output Fast Read using 4 bytes address (DOFR4BYTE), except that the
address bits are shifted in on two pins (pin DQ0 and pin DQ1) instead of only one.
