RE: Re: How to set clock related options?


But, I got a configuration from template(Akizuki H8/3068) :
           Real-time clock numerator : 1000000000
           Real-time clock denominator : 100
           Real-time clock base prescale : 8192 
           Real-time clock period :10
           OSC/Clock Frequency :20000000
It seems not the case .What does period really mean?
