Flash Write Command
Table 20-7.
This command is used to write the Flash contents.
The Flash memory plane is organized into several pages. Data to be written are stored in a load
buffer that corresponds to a Flash memory page. The load buffer is automatically flushed to the
Flash:
The Write Page command (WP) is optimized for consecutive writes. Write handshaking can be
chained; an internal address buffer is automatically increased.
