Volume Register (0x2)
Mute Enable (MUTE)
1 = Mute headphone outputs.
0 = Unmute headphone outputs.
Set MUTE = 1 to mute the headphone outputs (HPR,
HPL). The headphone output is muted on the first zero
crossing of the audio signal if zero-crossing detect is
enabled.
Table 13. Volume Control Settings
Slew-Rate Control Enable (SLEW)
1 = Enable slew-rate control.
0 = Disable slew-rate control.
The slew-rate control allows the headphone amplifiers to
smoothly slew between volume settings after a volume
change is made. Volume changes occur immediately
when the slew-rate control is disabled.
Volume Control (VOL(5:0))
VOL(5:0) controls the headphone amplifier volume
attenuation. Code 0x00 is full volume while 0x28 to 0x3F
is full attenuation. VMN sets to 1 when code 0x3F is pro-
grammed and the minimum volume is reached. Table
13 lists the volume attenuation settings for each code.
