Notes:
1.
MSInt_period = (msintPeriod + 1) * 125 us
msintPeriod[5:0] is set in MSINTPeriod register (assuming that value in 125usPrescaler
register has been adjusted to obtain 125 us period)
2.
ScanCycle_period = (ScanCycle + 1) * MSInt_period
3.
ScanCycle in conjunction with MSIntPeriod must be selected so that:
