Flash Read Command
Flash Write Command
This command is used to read the contents of the Flash memory. The read command can start
at any valid address in the memory plane and is optimized for consecutive reads. Read hand-
shaking can be chained; an internal address buffer is automatically increased.
Table 21-6.
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.
