Flash Read Command
Flash Write Command
This command is used to read the Flash contents. The memory map is accessible through this
command. Memory is seen as an array of words (32-bit wide). The read command can start at
any valid address in the memory plane. This address must be word-aligned. The address is
automatically incremented.
Table 14-19. Read Command
This command is used to write the Flash contents. The address transmitted must be a valid
Flash address in the memory plane.
The Flash memory plane is organized into several pages. Data to be written is 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.
Table 14-20. Write Command
Flash Write Page and Lock command (WPL) is equivalent to the Flash Write Command. How-
ever, the lock bit is automatically set at the end of the Flash write operation. As a lock region is
composed of several pages, the programmer writes to the first pages of the lock region using
Flash write commands and writes to the last page of the lock region using a Flash write and lock
command.
Flash Erase Page and Write command (EWP) is equivalent to the Flash Write Command. How-
ever, before programming the load buffer, the page is erased.
Flash Erase Page and Write the Lock command (EWPL) combines EWP and WPL
commands.
