On the input side of the TAS5731M device, the input signal to the mono amplifier can be selected from a mix, left
or right frame from an I²S, LJ, or RJ signal. The routing of the audio data which is presented on the SPK_OUTx
outputs must be configured with the PWM Output Mux Register (0x25).
Refer to the Mono Parallel Bridge Tied Load Application section for more details of the correct PBTL output
connection of the TAS5731M.
9.4.3 2.1 Mode
2.1 Mode is defined as the application of two Single ended channels and one BTL channel used in systems
where a third sub channel is required. Generally, both single-ended inputs drive the Left and Right channels,
while the BTL channel drives a low-frequency content channel called often Subwoofer. More information about
this can be found in the 2.1-Mode Support section.
