Flash Write Command
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 corre-
sponds to a Flash memory page. The load buffer is automatically flushed to the Flash:
before access to any page other than the current one
when a new command is validated (MODE = CMDE)
The Write Page command (WP) is optimized for consecutive writes. Write handshaking can be chained; an inter-
nal address buffer is automatically increased.
