Notes:
*
1 Two state access module : port, INT, CMT, SCI, etc.
*
2 Three state access module : WDT, CACHE, UBC, etc.
The execution state count is calculated using the following formula.
∑
indicates the number of
transfers by one activating source (count + 1 when CHNE bit is 1).
Execution state count = I · S
