Pointer Operation of K9S3208V0A
The K9S3208V0A has three modes to set the destination of the pointer. The pointer is set to "A" area by the "00h" command, to "B"
area by the "01h" 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.

Table 2. Pointer Status after each operation
* 01H command is valid just one time when it is used as a pointer for program/erase.
* Erase operation does not affect the pointer status. Previous pointer status is maintained.
