If I set the I2S peripheral on the nRF52 to mono, ie CHANNELS is either LEFT or RIGHT, what does it actually output? I'm sure it still toggles the LRCLK line to indicate left and right as that's part of the I2S protocol, however does it output the same channel on both halves, repeated, or does it output one channel during the correct half of LRCLK and zero on the other half of the clock? As far as I can tell, the manual doesn't say.
