29 / 78 page  Product Preview WM8594 w PP Rev 1.0 January 2007 29 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION 1:0 ADC_ FMT[1:0] 10 ADC Audio Interface Format 00 = Right Justified 01 = Left Justified 10 = I 2S 11 = DSP 3:2 ADC_ WL[1:0] 10 ADC Audio Interface Word Length 00 = 16-bit 01 = 20-bit 10 = 24-bit 11 = 32-bit (not available in Right Justified mode) 4 ADC_BCP 0 ADC BCLK Polarity 0 = ADCBCLK not inverted - data latched on rising edge of BCLK 1 = ADCBCLK inverted - data latched on falling edge of BCLK R13 ADC_CTRL1 0Dh 5 ADC_LRP 0 ADC LRCLK Polarity 0 = ADCLRCLK not inverted 1 = ADCLRCLK inverted Table 15 Audio Interface Control DAC FEATURES The WM8594 includes two 24-bit DACs with independent clocks and independent data inputs. The DACs include digital volume control with zero cross and soft mute, de-emphasis support, and the capability to select the output channels to be stereo or a range of mono options. The DACs are enabled by writing to DAC1_EN and DAC2_EN. REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R2 DAC1_CTRL1 02h 8 DAC1_EN 0 DAC1 Enable 0 = DAC disabled 1 = DAC enabled R7 DAC2_CTRL1 07h 8 DAC2_EN 0 DAC2 Enable 0 = DAC2 disabled 1 = DAC2 enabled Table 16 DAC Enable Control DIGITAL VOLUME CONTROL The WM8594 DACs include independent digital volume control, allowing the digital gain to be adjusted between -100dB and +12dB in 0.5dB steps. All four DAC channels can be controlled independently. Alternatively, global update bits allow the user to write all volume changes before the volume is updated. Volume control includes optional zero cross functionality. When zero cross is enabled, volume changes are not applied until the output level crosses VMID. Zero cross helps to prevent pop and click noise when changing volume settings. |
