Pointer Operation of KM29W32000
The KM29W32000 has three read modes to set the destination of the pointer. The pointer is set to "A" area by the "00h" command,
to "B" area by the "01" command, and to "C" area by the "50h" command. Table 1 shows the destination of the pointer, and figure 2
shows the block diagram of its operations.
