Production Data
DIGITAL MIXING
w
The ADC and DAC data can be combined in various ways to support a range of different usage
modes.
Data from either of the two ADCs can be routed to either the left or the right channel of the digital
audio interface. In addition, data from either of the digital audio interface channels can be routed to
either the left or right DAC. See "Digital Audio Interface" section for more information on the audio
interface.
DIGITAL MIXING PATHS
Figure 16 shows the digital mixing paths available in the WM8900 digital core.
Figure 16 Digital Mixing Paths
The polarity of each ADC output signal can be changed under software control using the
ADCL_DATINV and ADCR_DATINV register bits. The AIFADCL_SRC and AIFADCR_SRC
register bits may be used to select which ADC is used for the left and right digital audio interface
data. These register bits are described in Table 22.
