division ratios, and the division ratios
(e.g. when there are two divided clock types, which are the main and peripheral clocks, the
number of types will be H'02.)
(e.g. the number of division ratios to which the main clock can be set and the peripheral clock
can be set.)
Division ratio: The inverse of the division ratio, i.e. a negative number (e.g. when the clock is
divided by two, the value of division ratio will be H'FE. H'FE = D'-2)
The number of division ratios returned is the same as the number of division ratios and as
many groups of data are returned as there are types.
