Loop Counter Values in Programs and Watchdog Timer Overflow Interval Settings: The
values of a to h in the programs depend on the clock frequency. Table 19.9 indicates the values for
10 MHz. Values for other frequencies can be calculated as shown below, but use the settings in
table 19.10 for the value off.
