These 9 bits define the output frequency for TG2 on CH2. The frequency range is between
300 and 3400 Hz in 10 Hz intervals as shown in Table 18.
The output frequency is calculated using the following formula:
Binary data for CR14-B0, CR15-B7 to B0
= (Output Frequency [Hz])/10
The following example shows how to program the output frequency when the intended
frequency is 1500 Hz;
Ex) (Output Frequency [Hz]) / 10 = 1500/10 = 150d = 10010110b
Note that the operations are not guaranteed when these bits define a frequency out of a band
between 300 and 3400 Hz.
