关於5715 stereo, mono问题？

你好：

1.设定0x25，以及Pin 8脚上的PBTL就可以了,这个Pin要拉高。详细解释可以参照如下描述：

The TAS5715 supports parallel BTL (PBTL) mode with OUT_A/OUT_B (and OUT_C/OUT_D) connected before
the LC filter. In order to put the part in PBTL configuration, drive PBTL (pin 8) HIGH. This synchronizes the
turnoff of half-bridges A and B (and similarly C/D) if an overcurrent condition is detected in either half-bridge.
There is a pulldown resistor on the PBTL pin that configures the part in BTL mode if the pin is left floating.
PWM output multiplexers should be updated to set the device in PBTL mode. Output Mux Register (0x25) should
be written with a value of 0x01 10 32 45. Also, the PWM shutdown register (0x19) should be written with a value
of 0x3A.

2.你说的那几个mix寄存器不用设置，都与这个无关，很多都是只读寄存器，保持默认就好。

3.你手上有板子，可以设置的试一下，你就明白了。
