Default

Bits[3:1]

Select internally generated

clock

Selects the frequency of the internally generated clock to be output on the MCLK_OUT pin.

000

000b = crystal clock from internal PLL

001b = audio processor clock (122.88 MHz/2560 × FS)

010b = engine clock (49.152 MHz/1024 × FS)

011b = SRC clock/2 (24.576 MHz/512 × FS)

1xxb = modulator clock (6.144 MHz/128 × FS)

Bit[0]

PLL enable

Enables the PLL.

0b = PLL bypassed

1b = PLL enabled

Bit[7]

HP1 mute

When set to 1, mutes the headphone output immediately without ramping.

0b = unmuted

1b = mute

Bit[6]

HP1 short-circuit protect

Enables the short-circuit protection for the headphone amplifier.

0b = disabled

1b = enabled

Bit[5]

HP1 tristate

Disables tristating of the headphone amplifier.

0b = enabled

1b = disabled

Bits[4:0]

Headphone 1 gain/attenuation

Used to apply analog attenuation to the headphone amplifier.

00000

00000b = 0 dB

00001b = −1.5 dB

00010b = −3 dB

…

11101b = −43.5 dB

11110b = −45 dB

11111b = +1.5 dB

Address 0x000C Serial Port Control 2 Register (Default: 0x8004)

It should be noted that SDIN3, LRCLK0, BCLK0, LRCLK1, BCLK1, LRCLK2, and BCLK2 can also be used as SPDIF_IN0, SPDIF_IN1,

SPDIF_IN2, SPDIF_IN3, SPDIF_IN4, SPDIF_IN5, and SPDIF_IN6.
