Question on esp8266 audioOut PDM pin #214

Description

@jim80

From the docs
"Defines for ESP8266
MODDEF_AUDIOOUT_I2S_PDM -- If zero, PCM samples are transmitted over I2S. If non-zero, samples are transmitted using PDM. Set to 32 for no oversampling, 64 for 2x oversampling, and 128 for 4x oversampling. Default is 0."

I take this to mean that setting a non zero value will result in a PDM output on a single pin.
Am I correct? If so, which pin will it be output to?

Many thanks!
Cheers!
JIm.
