external source). When the clocks are in slave mode, they
must be synchronous to SYS_MCLK. For this reason the

The I2S_LRCLK and I2S_SCLK can be programmed as
(SCLKFREQ = 0; SCLK_INV = 0; DLEN = 1; I2S_MODE = 0; LRALIGN = 0; LRPOL = 0)
(SCLKFREQ = 0; SCLK_INV = 0; DLEN = 1; I2S_MODE = 0; LRALIGN = 1; LRPOL = 0)
SCLKFREQ = 0; SCLK_INV = 0; DLEN = 1; I2S_MODE = 1; LRALIGN = 1; LRPOL = 0)
