The duty cycle of the divided system clock differs according to the ROPCR setting value m.
When m is an even number, the duty cycle is 50 %. When m is an odd number, the duty cycle
is determined according to the following formula:
2m + 4
m + 3
× 100 (%)
When m is an odd number, the larger is the setting value m, the closer is the duty cycle to 50
%.
