(Figure 4-2). If an attempt is made to write to the array
when the hardware write protection has been enabled,
the device will acknowledge the command, but no data
will be written. The write cycle time must be observed
even if the write protection is enabled.
FIGURE 4-1:
BYTE WRITE
Note:
Page write operations are limited to writing
bytes within a single physical page,
regardless of the number of bytes actually
being written. Physical page boundaries
start at addresses that are integer multi-
ples of the page buffer size (or ‘page size’)
and end at addresses that are integer mul-
tiples of [page size – 1]. If a Page Write
command attempts to write across a phys-
ical page boundary, the result is that the
data wraps around to the beginning of the
current page (overwriting data previously
stored there), instead of being written to
the next page, as might be expected. It is
therefore necessary for the application
software to prevent page write operations
that would attempt to cross a page
boundary.
