*Address bit A23 is “Don’t Care.”
Chip Select (S) must be driven High after the eighth bit of the last data byte has been
latched in, otherwise the Quad Input Fast Program (QIFP) instruction is not executed.
As soon as Chip Select (S) is driven High, the self-timed Page Program cycle (whose
duration is tPP) is initiated. While the Quad Input Fast Program (QIFP) cycle is in progress,
the Status Register may be read to check the value of the Write In Progress (WIP) bit. The
Write In Progress (WIP) bit is 1 during the self-timed Page Program cycle, and 0 when it is
completed. At some unspecified time before the cycle is completed, the Write Enable Latch
(WEL) bit is reset.
A Quad Input Fast Program (QIFP) instruction applied to a page that is protected by the
Block Protect (BP3, BP2, BP1, BP0 and TB) bits is not executed.
A Quad Input Fast Program cycle can be paused by mean of Program/Erase Suspend
(PES) instruction and resumed by mean of Program/Erase Resume (PER) instruction.

Quad Input Extended Fast Program
The Quad Input Extended Fast Program (QIEFP) instruction is very similar to the Quad
Input Extended Fast Program (QIFP), except that the address bits are shifted in on four pins
(pin DQ0, pin DQ1, pin W/VPP/DQ2 and pin HOLD/DQ3) instead of only one.
