Yamaha OPL3-SA3 YMF715E, Master Volume Lch R/W, Master Volume Rch R/W, MIC Volume R/W

YMF715E

Master Volume Lch (R/W):

	Index	D7	D6	D5	D4	D3	D2	D1	D0
	07h	MVLM	-	-	-	MVL3	MVL2	MVL1	MVL0
	This register specifies the master volume of left channel.
	MVLM...		Setting to “1” to this bit makes Master Volume Left Channel muted.
	MVL3-0...		These bits determine the attenuation level of Master Volume Left
			Channel by -2dB step. When all bits are set to “0”, volume is maximum
			(0dB) and when all bits are set to “1”, volume is minimum (-30dB).
	default : 07h (-14dB)
	Notice)
	During the power on reset and power down/save mode, master volume is automatically
	muted, so all audio sources can not be heard. In resuming from power down/save mode, it is
	still muted.
Master Volume Rch (R/W):
	Index	D7	D6	D5	D4	D3	D2	D1	D0
	08h	MVRM	-	-	-	MVR3	MVR2	MVR1	MVR0
	This register specifies the master volume of right channel.
	MVRM...		Setting to “1” to this bit makes Master Volume Right Channel muted.
	MVR3-0...		These bits determine the attenuation level of Master Volume Right
			Channel by -2dB step. When all bits are set to “0”, volume is maximum
			(0dB) and when all bits are set to “1”, volume is minimum (-30dB).
	default : 07h (-14dB)
	Notice)
	During the power on reset and power down/save mode, master volume is automatically
	muted, so all audio sources can not be heard. In resuming from power down/save mode, it is
	still muted.
MIC Volume (R/W):
	Index	D7	D6	D5	D4	D3	D2	D1	D0
	09h	MICM	-	-	MCV4	MCV3	MCV2	MCV1	MCV0
	This register specifies the master volume of MIC.
	MICM...		Setting to “1” to this bit makes Mic Volume muted.
	MCV4-0...		These bits determine the gain level of Mic volume by -1.5dB step. When
			all bits are set to “0”, volume is maximum(+12dB) and when all bits are
			set to “1”, volume is minimum (-34.5dB).
	default : 88h
