Device Operations
Flash Read Command
Several commands on the Flash memory are available. These commands are summarized in
Table 20-3 on page
face running several read/write handshaking sequences.
When a new command is executed, the previous one is automatically achieved. Thus, chaining
a read command after a write automatically flushes the load buffer in the Flash.
In the following tables:
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.
