Description:
Set the minimum period for busy detection to 700 (7 seconds).
VC
Volume Control vol_level
Controls the energy level of all the output generators (playback, tone generation, and voice synthe-
sis), with one command. The resolution is ±3 dB.
The actual output level is composed of the tunable level variable, plus the vol_level. The valid range
for the actual output level of each output generator is defined in Table 2-5.
For example, if the tunable variable VCD_LEVEL (parameter number 21) is 6, and vol_level is –2, then
the output level equals VCD_LEVEL + vol_level = 4.
