Formula: When using a clock frequency not shown in tables 19.9 (1) and (2), follow the formula
below. The calculation is based on a clock frequency of 10 MHz.
After calculating a(f) and d(f) in the decimal system, omit the first decimal figures, and convert
them to the hexadecimal system, so that a(f) and d(f) are set to 20 s or less and 10 ms or less,
respectively.
After calculating b(f) and c(f) in the decimal system, raise the first decimal figures, and convert
them to the hexadecimal system, so that b(f) and c(f) are set to 4 s or more and 2 s or more,
respectively.
Examples for a program running in on-chip memory (RAM) at a clock frequency of 12 MHz:
