PRODUCTION DATA.
When it is required to update the DAC digital filter coefficients or beep generator during play, care must be taken to avoid click and pop noise or even a possible oscillation noise. These artifacts can occur if the DAC coefficients are updated without following the proper update sequence. The correct sequence is shown in Figure 6-18. The values for times listed in Figure 6-18 are conservative and should be used for software purposes.
There is also an adaptive mode, in which DAC coefficients can be updated while the DAC is on. For details, see Section 6.3.10.1.3.
