Volume Control The signal volume can be controlled digitally, across a gain and attenuation range of -95.25dB to 0dB (0.375dB steps). The level of attenuation is specified by an eight-bit code, ‘DACVOL_x’, where ‘x’ is L, or R. The value “00000000” indi- cates mute; other values select the number of 0.375dB steps above -95.625dB for the volume level. The Volume Update bits control the updating of volume control data; when a bit is written as ‘0’, the Left Volume control associated with that bit is updated whenever the left volume register is written and the Right Volume control is updated when ever the right volume register is written. When a bit is written as ‘1’, the left volume data is placed into an internal holding register when the left volume register is written and both the left and right volumes are updated when the right volume register is written. This enables a simultaneous left and right volume update The output path may be muted automatically when a long string of zero data is received. The length of zeros is pro- grammable and a detection flag indicates when a stream of zero data has been detected.
