SISPOL

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 * Fsi

1 - 128 * Fsi

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

1 - MSB of SDIN data occurs in the second ISCLK period after the ILRCK edge

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
