These bits define the output frequency from TG2 on CH1. The frequency is between 300
and 3400Hz at 10Hz intervals. The values written to these bits determine the frequency as
shown in the following equation. Refer to Table 11.
Binary data for CR7-B0, CR8-B7 to B0
= (Output Frequency [Hz])/10
Below is an example of how these bits are programmed when the intended frequency is
1500Hz;
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.
