If they matter in slave mode, what do they control, considering that the external code is driving FSYNC and thus controls its width. +\ Page 1506 - For I2S_RXDATA, the connection from the pin driver to RX_DATA_IN(18) is shown going to the (disabled) output driver. I think it should come from the input (left-pointing triangle) instead. +\ Page 1506 - The "18" and "19" notation is unexplained and unclear. I sort of think that 18 means the Rx direction and 19 the Tx direction. If so, and the diagram is correct, then you cannot drive FSYNC from the Tx direction. If that is the case, it ought to be explained elsewhere too. In particular, if you can't drive FSYNC from Tx, what are the FWID and FPER fields in SSPA_TX_SP_CTRL for? +\ Page 1506 - The diagram shows the ENB for the I2S_BITCLK driver coming from M/S_19 in SSPA. But the Master/Slave bits in both SSPA_TX_SP_CTRL and SSPA_RX_SP_CTRL have no effect on whether BITCLK is driven. It seems to be controlled by bit 8 in SSPA_AUD_CTRL0 (which is misnamed as enabling the SYSCLK Divider, not the BITCLK output. Which makes me wonder what enables the I2S_FSYNC signal, which is shown as being enabled along with I2S_BITCLK. But I can't seem to get FSYNC to come out. +\ What is the relationship between Rx master mode and Tx master mode with regards to whether FSYNC is driven? Empirically, if I turn on and enable the Rx portion, FSYNC comes on, but if I then turn on the Tx portion, FSYNC turns off until I enable the Tx portion. After that, Tx seems to control FSYNC and nothing I do seems to let Rx control it. +\ Page 1502 - S_RST is listed as W, but empirically it is readable. When you write 1 to it, the 1 sticks and you have to write 0 again. It's unclear which of the registers it really resets. It doesn't reset the register it is in. +\ Page 1498 - The data transmit register is listed as RO.
