The instruction
 0Bh (ExtAdd=0) is followed by a 3-byte address (A23-A0) or
 0Bh (ExtAdd=1) is followed by a 4-byte address (A31-A0) or
 0Ch is followed by a 4-byte address (A31-A0)
The address is followed by zero or eight dummy cycles depending on the latency code set in the
Configuration Register. The dummy cycles allow the device internal circuits additional time for accessing the
initial address location. During the dummy cycles the data value on SO is “don’t care” and may be high
impedance. Then the memory contents, at the address given, are shifted out on SO.
The maximum operating clock frequency for FAST READ command is 133 MHz.
The address can start at any byte location of the memory array. The address is automatically incremented to
the next higher address in sequential order after each byte of data is shifted out. The entire memory can
therefore be read out with one single read instruction and address 000000h provided. When the highest
address is reached, the address counter will wrap around and roll back to 000000h, allowing the read
sequence to be continued indefinitely.
