RES: To recover from a shutdown, the output stage requires VALID to go low.
AUT: The power stage can auto-recover from a shutdown.
BTL: Bridge-tied load configuration
SE: Single-ended configuration
The headphone configuration controls are identical to the speaker configuration controls. The headphone
configuration control settings are used in place of the speaker configuration control settings for channels 1
and 2 when the headphones are selected. However, only one configuration setting for headphones is
used, and that is the default setting.
The TAS5518C can be configured to comply with various audio systems: 5.1-channel system, 6-channel
system, 7.1-channel system, and 8-channel system.
The audio system configuration is set in the general control register (0xE0). Bits D31–D4 must be zero
and D0 is don't care.
D3
Must always be 0 (default). Note that subwoofer cannot be used as lineout when PSVC is
enabled. (D3 is a write-only bit)
D2
Enables/disables power-supply volume control
D1
Sets number of speakers in the system, including possible line outputs
D3–D1 must be configured for the audio system in the application, as shown in Table 3-7.
