Quad Page Program
The Quad Page Program instruction allows many bytes to be
programmed in the memory by using four I/O pins (SIO

performance and the effectiveness of application that have slow
clock speed <20MHz. For system with faster clock, this
instruction can’t provide more actual favors, because the required
internal page program time is far more than the time data flows in.
Therefore, we suggest that user can execute this command while

Prior to Quad Page Program operation, the Write Enable (WREN)
instruction must be executed and Quad Enable (QE) bit of Status
Register-2 must be set “1”. The other function descriptions are as
same as standard Page Program. See Figure 11 for the Quad
Page Program sequence.
