4. To specify the maximum programming time (t_P(max)) in the 32-byte programming
flowchart, set the maximum value (403) for the maximum programming count (N).
The wait time after P bit setting (z) should be changed as follows according to the
programming counter value.
Programming counter value of 1 to 4: z = 150 µs
Programming counter value of 5 to 403: z = 500 µs
5. For the maximum erase time (t_E(max)), the following relationship applies between the
wait time after E bit setting (z) and the maximum erase count (N):
t_E(max) = Wait time after E bit setting (z) × maximum erase count (N)
To set the maximum erase time, the values of z and N should be set so as to satisfy the
above formula.
Examples: When z = 5 [ms], N = 60 times
When z = 10 [ms], N = 30 times
18.3 Operational Timing
This section shows timing diagrams.
18.3.1 Bus Timing
Bus timing is shown as follows:
• Basic bus cycle: two-state access
Figure 18.7 shows the timing of the external two-state access cycle.
• Basic bus cycle: three-state access
Figure 18.8 shows the timing of the external three-state access cycle.
• Basic bus cycle: three-state access with one wait state
Figure 18.9 shows the timing of the external three-state access cycle with one wait state
inserted.
