Pointer control for “00h”, “01h” and “50h”
the pointer, and Figure 17 is a block diagram of their operations.
Table 7. Pointer Destination
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.

region C.
Read Mode
The device has three Read modes which set the destination of the pointer. Table 7 shows the destination of
The “00h” command must be input to set the pointer back to region A when the pointer is pointing to
To program region C only, set the start point to region C using the 50h command.
