slave. SCLK and LRCLK are chip inputs. The clock
configuration controls in this register are ignored in slave
mode.
Override I
1 - Override the SAI_MSTR_CLK_CFG from the I
and use the I2SClkDiv Register settings.
0 - Use the I2S SAI_MSTR_CLK_CFG signals.
Drop SCLK clocks.
1 - When in 64x mode, drop 8 SCLKs.
0 - Do not drop SCLKs.
SCLK polarity. Defines the SCLK edge that aligns to
LRCLK transitions.
1 - LRCLK transitions on the falling SCLK edge.
0 - LRCLK transitions on the rising SCLK edge.
LRCLK divide select.
00 - LRCK = SCLK / 32
