33 / 103 page  Production Data WM8580 w PD Rev 4.5 February 2008 33 DAC DIGITAL VOLUME CONTROL The DAC volume may also be adjusted in the digital domain using independent digital attenuation control registers REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION 7:0 LDA1[7:0] 11111111 (0dB) Digital Attenuation control for DAC1 Left Channel (DACL1) in 0.5dB steps. See Table 23 R20 Digital Attenuation DACL 1 14h 8 UPDATE Not latched Controls simultaneous update of all Attenuation Latches 0 = Store LDA1 in intermediate latch (no change to output) 1 = Apply LDA1 and update attenuation on all channels 7:0 RDA1[6:0] 11111111 (0dB) Digital Attenuation control for DAC1 Right Channel (DACR1) in 0.5dB steps. See Table 23 R21 Digital Attenuation DACR 1 15h 8 UPDATE Not latched Controls simultaneous update of all Attenuation Latches 0 = Store RDA1 in intermediate latch (no change to output) 1 = Apply RDA1 and update attenuation on all channels. 7:0 LDA2[7:0] 11111111 (0dB) Digital Attenuation control for DAC2 Left Channel (DACL2) in 0.5dB steps. See Table 23 R22 Digital Attenuation DACL 2 16h 8 UPDATE Not latched Controls simultaneous update of all Attenuation Latches 0 = Store LDA2 in intermediate latch (no change to output) 1 = Apply LDA2 and update attenuation on all channels. 7:0 RDA2[7:0] 11111111 (0dB) Digital Attenuation control for DAC2 Right Channel (DACR2) in 0.5dB steps. See Table 23 R23 Digital Attenuation DACR 2 17h 8 UPDATE Not latched Controls simultaneous update of all Attenuation Latches 0 = Store RDA2 in intermediate latch (no change to output) 1 = Apply RDA2 and update attenuation on all channels. 7:0 LDA3[7:0] 11111111 (0dB) Digital Attenuation control for DAC3 Left Channel (DACL3) in 0.5dB steps. See Table 23 R24 Digital Attenuation DACL3 18h 8 UPDATE Not latched Controls simultaneous update of all Attenuation Latches 0 = Store LDA3 in intermediate latch (no change to output) 1 = Apply LDA3 and update attenuation on all channels. 7:0 RDA3[7:0] 11111111 (0dB) Digital Attenuation control for DAC3 Right Channel (DACR3) in 0.5dB steps. See Table 23 R25 Digital Attenuation DACR3 19h 8 UPDATE Not latched Controls simultaneous update of all Attenuation Latches 0 = Store RDA3 in intermediate latch (no change to output) 1 = Apply RDA3 and update attenuation on all channels. 7:0 MASTDA[7:0] 11111111 (0dB) Digital Attenuation control for all DAC channels in 0.5dB steps. See Table 23 R28 Master Digital Attenuation 1Ch 8 UPDATE Not latched Controls simultaneous update of all Attenuation Latches 0 = Store gain in intermediate latch (no change to output) 1 = Apply gain and update attenuation on all channels. Table 22 Digital Attenuation Registers Note: The volume update circuit of the WM8580 has two sets of registers; LDAx and RDAx. These can be accessed individually, or simultaneously by writing to MASTDA – Master Digital Attenuation. Writing to MASTDA will overwrite the contents of LDAx and RDAx. |
