APPLICATION NOTES AND COMMENTS
(1)
Prohibition of unspecified commands
The operation commands are listed in Table 3. Input of a command other than those specified in Table 3 is
prohibited. Stored data may be corrupted if an unknown command is entered during the command cycle.
(2)
Restriction of command while Busy state
During Busy state, do not input any command except 70H and FFH.
(3)
Pointer control for 00H, 01H and 50H
The device has three Read modes which set the destination of the pointer. Table 7 shows the destination of
the pointer, and Figure 14 is a block diagram of their operations.

The pointer is set to region A by the 00H command, to region B by the 01H command, and to region C by the
50H command.
(Example)
The 00H command must be input to set the pointer back to region A when the pointer is pointing to region
C.
To program region C only, set the start point to region C using the 50H command.
