 ChibiOS uses GPIOv1 for the F103, which only knows of one alternate function.
 On 'larger' STM32s, GPIOv2 or GPIOv3 are used; with them it is also necessary to configure `AUDIO_PWM_PAL_MODE` to the correct alternate function for the selected pin, timer and timer-channel.
 
+You can also use the Complementary output (`TIMx_CHyN`) for PWM on supported controllers.  To enable this functionality, you will need to make the following changes:
+```c
+// config.h:
+#define AUDIO_PWM_COMPLEMENTARY_OUTPUT
+```
