Table 20 Tone Generator Frequency Setting (CH2RING bit = “0”)
When the CH2RING (CR11-B7) bit is cleared, this 9-bit field is valid and determines the
output frequency from tone generator 1 on channel 2. The frequency range is between 300
and 3400 Hz at 10 Hz intervals as shown in Table 20.
The output level is calculated using the following formula.
Binary data for CR16-B0, CR17-B7 to B0
= (Output Frequency [Hz])/10
The following is an example of how to program this register field 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.
When the CH2RING (CR11-B7) bit is set, the setting of the CH2TG1_8 (CR16-B0) bit and
the CH2TG1_7 to CH2TG1_6 (CR16-B7 to B6) bits are ignored, and the CH2TG1_5 to
CH2TG1_0 (CR16-B5 to B0) field defines the ringing tone frequency.
When the CH2RING (CR11-B7) bit is set, the frequency range is between 15 and 50 at 1
Hz intervals as shown in Table 21.
The output frequency is calculated using the following formula.
Binary data for CR17-B5 to B0
= (Output Frequency [Hz])
