... Pointer Operation: The 29F0408 has three modes to set the destination of the pointer. The pointer is set to “A” area by the “00h” com- mand, to “B” area by the “01h” command, and to “C” area by the “50h” command. The Destination Pointer Table shows the destination of the pointer, and the block diagram shows the diagram of its operation ...
