Loop Counter Values in Programs and Watchdog Timer Overflow Interval Settings: The
setting of #a, #b, #c, #d, and #e values in the programs depends on the clock frequency. Tables
20.9 (1) and (2) indicate sample loop counter settings for typical clock frequencies. However, #e is
set according to table 20.10.
As a software loop is used, calculated values including percent errors may not be the same as
actual values. Therefore, the values are set so that the total programming time and total erase time
do not exceed 1 ms and 30 s, respectively.
The maximum number of writes in the program, N, is set to 6.
