36 / 60 page ![]() SPI(x1/x2/x4) NAND Flash 1G 36 10.8 Program Load Random Data Quad IO (72H) The Program Load Random Data Quad IO command (72H) is similar to the Program Load Random Data x4 command (C4H) but with the capability to input the 4 dummy bits, and a 12-bit column address 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 for the program load random data x4 command. See Figure10-6 for details. This command is only available during internal data move sequence. Figure10-6.
