Doing some study of the latest ESP32 Technical ref manual ... .I am looking at figure 8.29 (I2S_CLKM_CONF_REG) and I see that bit 20 is reserved. However, when I look in the "i2s_struct.h" (
https://github.com/espressif/esp-idf/bl ... uct.h#L390) I seem to see it defined is "clk_en".

Yes, and that wouldn't be the only bit anywhere that would be reserved in the TRM but that has a name in the headers. These bits have behaviour that is usually only intended for debugging, and are in the headers so we can do that easily without resorting to hacks, but we don't want to have them documented because they do not have use outside of Espressif.
