32 / 57 page ![]() SPI(x1/x2/x4) NAND Flash 2G 32 11.3 Program Load x4 (PL x4) (32H) The Program Load x4 command (32H) is similar to the Program Load command (02H) but with the capability to input the data bytes by four pins: SIO0, SIO1, SIO2, and SIO3. The command sequence is shown below. The Quad Enable bit (QE) of feature (B0[0]) must be set to enable the program load x4 command. Figure11-2.
