Read Write
0 Enable sound source generation. Does not have any effect on operation.
1 Sound source generation start wait. Start sound source generation.
Notes:
−
When "1" is written to this bit, SWFG starts sound source generation in accordance with sound
source specification settings.
−
SWFG is when "1" is written to this bit while a previous sound source generation is in progress,
consecutive sound source generation starts when generation of the previous sound source is
complete.
−
This bit is automatically cleared when the desired sound source generation starts.
−
Writing "0" in this bit does not stop sound source generation. For information about stopping
sound source generation, see 4.1.
−
Sound source generation start wait cannot be canceled.
−
Changing sound source specifications during sound source generation start standby can result in
sound source generation starting while implementation of changes is in progress, resulting in
unintended sound being produced. Set sound source specifications while sound source
generation is enabled.
