Command
multiplication ratios, and multiplication ratio
One hundredth of the value (e.g. when the value is 19,200 bps, the bit rate is H'00C0, which is
192.)
This is valid to the hundredths place and represents the value in MHz multiplied by 100 (e.g.
when the value is 64 MHz, the input frequency is H'1900 (= 6400)).
device can be set.
operating frequency
Multiplication ratio (1 byte): The value of the multiplication ratio (e.g. when the clock
frequency is multiplied by four, the multiplication ratio will be H'04.)
Division ratio: The inverse of the division ratio, as a negative number (e.g. when the clock
frequency is divided by two, the value of division ratio will be H'FE. H'FE = [-2])
