SIMS - Master/Slave Mode Selector
Default = ‘0’
0 - Serial audio input port is in Slave Mode
1 - Serial audio input port is in Master Mode
SISF - ISCLK frequency (for Master Mode)
Default = ‘0’
0 - 64*Fs
1 - 128*Fs
SIRES1:0 - Resolution of the input data, for right-justified formats
Default = ‘00’
00 - 24-bit resolution
01 - 20-bit resolution
10 - 16-bit resolution
11 - Reserved
SIJUST - Justification of SDIN data relative to ILRCK
Default = ‘0’
0 - Left-justified
1 - Right-justified
SIDEL - Delay of SDIN data relative to ILRCK, for left-justified data formats
Default = ‘0’
0 - MSB of SDIN data occurs in the first ISCLK period after the ILRCK edge (Left-Justified Mode)
1 - MSB of SDIN data occurs in the second ISCLK period after the ILRCK edge (I²S Mode)
SISPOL - ISCLK clock polarity
Default = ‘0’
0 - SDIN sampled on rising edges of ISCLK
1 - SDIN sampled on falling edges of ISCLK
SILRPOL - ILRCK clock polarity
Default = ‘0’
0 - SDIN data is for the left channel when ILRCK is high
1 - SDIN data is for the right channel when ILRCK is high
