Placing Flash Memory in Read/Reset State
This section explains the procedure for entering the read/reset command to
place the Flash memory in read/reset state.
■ Placing Flash Memory in Read/Reset State
•
To place the Flash memory in the read/reset state, send read/reset commands in the
command sequence table from the CPU to the Flash memory.
•
Since the read/reset state is the initial state of the Flash memory, the Flash memory always
enters this state after power-on or the normal termination of a command. The read/reset
state is also regarded as the command input wait state.
•
In the read/reset state, data in the Flash memory can be read by a read access to the Flash
memory.
•
In the case of a read access to the Flash memory, no read/reset commands are required. If a
command does not terminate normally, use a read/reset command to initialize the automatic
algorithm.
