35 / 60 page ![]() SPI(x1/x2/x4) NAND Flash 1G 35 10.7 Program Load Random Data x4 (C4H/34H) The Program Load Random Data x4 command (C4H/34H) is similar to the Program Load Random Data command (84H) 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 for the program load random data x4 command. See Figure10-5 for details. Those two commands are only available during internal data move sequence. Figure10-5.
