SPI(x1/x2/x4) NAND Flash

8.7 Read From Cache Quad IO (EBH)

The Read from Cache Quad IO command is similar to the Read from Cache x4 command but with the capability to input

the 4 dummy bits, followed a 12-bit column address for the starting byte address and a dummy byte by SIO0, SIO1, SIO3,

SIO4, each bit being latched in during the rising edge of SCLK, then the cache contents are shifted out 4-bit per clock

cycle from SIO0, SIO1, SIO2, SIO3. The first byte addressed can be at any location. The address is automatically

incremented to the next higher address after each byte of data is shifted out until the boundary wrap bit. The Quad Enable

bit (QE) of feature (B0[0]) must be set to enable the read from cache quad IO command.
