Table 1. Destination of the pointer
Pointer Operation of K9F6408U0M
The K9F6408U0M 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.
