Synthesizer frequency is expressed as a four digit decimal number (freq) to be multiplied by 0.1 Hz and an base 10 exponent (range). If the effective frequency is less than 10 kHz its phase is synchronized corresponding to the variable phase. Phase may be in a range from -360 deg to +360 deg with a resolution of 0.1 deg, so the resulting numbers to be stored are in a range of -3600 to +3600.
Example:
Assume the value of freq is 2345 (decimal) and the value of phase is 900. If range == 0 the effective frequency is 234.5 Hz with a phase of +90 deg. If range == 1 the synthesizer will generate a 2345 Hz output frequency and so on.
Limitations:
If freq == 0 the synthesizer is disabled. If range == 0 the least significant digit of freq is limited to 0, 3, 5 or 6. The resulting frequency is shown in the examples below:
If range == MAX_SYNTH_RANGE the value of freq must not exceed 1000, so the output frequency is limited to 10 MHz (see MAX_SYNTH_FREQ_VAL).
