Notes: 1. Set the times according to the program/erase algorithms.
21.3
This section shows timing diagrams.
21.3.1
Bus timing is shown as follows:
Basic bus cycle: two-state access
Figure 21.4 shows the timing of the external two-state access cycle.
Basic bus cycle: three-state access
Figure 21.5 shows the timing of the external three-state access cycle.
2. Programming time per 128 bytes. (Shows the total time the P1 bit or P2 bit in the flash
