and the number of frequencies.
frequency types
(e.g. when there are two operating clock frequency types, which are the main and peripheral
clocks, the number of types will be H'02.)
multiplied or divided clock frequency.
The minimum and maximum values of the operating clock frequency represent the values in
MHz, valid to the hundredths place of MHz, and multiplied by 100. (e.g. when the value is
17.00 MHz, it will be 2000, which is H'07D0.)
frequencies.
There are as many pairs of minimum and maximum values as there are operating clock
frequencies.
