ratios and the multiplication ratios
(e.g. when there are two multiplied clock types, which are the main and peripheral clocks, the
number of types will be H'02.)
(e.g. the number of multiplication ratios to which the main clock can be set and the peripheral
clock can be set.)
multiplier is four, the value of multiplication ratio will be H'04.)
Division ratio: The number of multiplication ratios returned is the same as the number of
multiplication ratios and as many groups of data are returned as there are types.
