Does the ESP32-C6 support PDM RX or not?

I'm trying to hookup a microphone to an ESP32-C6. However, I'm getting mixed information whether or not a PDM microphone is supported or not.

Here it is said to exist (PDM RX):
- Section 29.10.1 of the Techincal Reference Manual says

ESP32-C6 I2S supports both TDM RX mode and PDM RX mode.

- The issue for the ESP32-C6 support status also lists PDM RX.

This makes me think it is NOT supported:
- The table for the modes of the I2S peripheral says none for PDM RX for the ESP32C6
- The soc_caps config file for the esp32c6 on master doesn't contain SOC_I2S_SUPPORTS_PDM_RX


So, does this mean that software support is not ready for PDM RX, or does the actual hardware of the C6 not contain support for PDM RX?

Thanks
