Pointer control for “00H”, “01H” and “50H”
The device has three Read modes which set the destination of the pointer. Table 8 shows the destination of
the pointer, and Figure 19 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.
