PRODUCTION DATA.
For the speaker outputs, the analog volume control has a range from 0 dB to –78 dB in 0.5-dB steps for most of the useful range plus mute, as seen in Table 6-24. The implementation includes soft-stepping logic.
Routing the left-channel DAC output signal to the left-channel analog volume control is done by writing to page 1 / register 35, bit D6. Routing the right-channel DAC output signal to the right-channel analog volume control is done by writing to page 1 / register 35, bit D2. Changing the left-channel analog volume for the speaker is controlled by writing to page 1 / register 38, bits D6–D0. Changing the right-channel analog volume for the speaker is controlled by writing to page 1 / register 39, bits D6–D0.
Routing the signal from the output of the left-channel analog volume control to the input of the left-channel speaker amplifier is done by writing to page 1 / register 38, bit D7. Routing the signal from the output of the right-channel analog volume control to the input of the right-channel speaker amplifier is done by writing to page 1 / register 39, bit D7.
The analog volume-control soft-stepping time is based on the setting in page 0 / register 63, bits D1–D0.
