the last data byte has been latched in; otherwise the Page Program command is not executed.
As soon as CS# is driven high, the self-timed Page Program cycle (whose duration is tPP) is initiated. While the Page
Program 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 is 0 when it is completed. At some
unspecified time before the cycle is completed, the Write Enable Latch (WEL) bit is reset.
A Page Program (PP) command applied to a page which is protected by the Block Protect (BP4, BP3, BP2, BP1, BP0)
is not executed.
