PRODUCTION DATA.
For the headphone 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, which is shown in Table 6-24. This volume control includes soft-stepping logic. Routing the left-channel DAC output signal to the left-channel analog volume control occurs by writing to page 1 / register 35, bit D6. Routing the right-channel DAC output signal to the right-channel analog volume control occurs by writing to page 1 / register 35, bit D2.
Changing the left-channel analog volume for the headphone is controlled by writing to page 1 / register 36, bits D6–D0. Changing the right-channel analog volume for the headphone is controlled by writing to page 1 / register 37, bits D6–D0. Routing the signal from the output of the left-channel analog volume control to the input of the left-channel headphone power amplifier occurs by writing to page 1 / register 36, bit D7. Routing the signal from the output of the right-channel analog volume control to the input of the right-channel headphone power amplifier occurs by writing to page 1 / register 37, bit D7.
The analog volume-control soft-stepping time is based on the setting in page 0 / register 63, bits D1–D0.
