• Manufacturer: Cirrus Logic

8.6
For all bits in this register, a “1” means the associated interrupt condition has occurred at least once since the register
was last read. A ”0” means the associated interrupt condition has NOT occurred since the last reading of the register.
Reading the register resets all bits to 0, unless the interrupt mode is set to level and the interrupt source is still true.
Status bits that are masked off in the associated mask register will always be “0” in this register. This register defaults
to 00h.

Interrupt 1 Status (7h) (Read Only)
SIJUST - Justification of SDIN data relative to ILRCK
SIDEL - Delay of SDIN data relative to ILRCK, for left-justified data formats
SISPOL - ISCLK clock polarity
SILRPOL - ILRCK clock polarity
TSLIP - AES3 transmitter source data slip interrupt
EFTC - E to F C-buffer transfer interrupt.
Default = ‘0’
0 - Left-justified
1 - Right-justified
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 (I
Default = ‘0’
0 - SDIN sampled on rising edges of ISCLK
1 - SDIN sampled on falling edges of ISCLK
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
In data flows where OMCK, which clocks the AES3 transmitter, is asynchronous to the data source,
this bit will go high every time a data sample is dropped or repeated. When TCBL is an input, this bit
will
go high on receipt of a new TCBL signal.
The source for this bit is true during the E to F buffer transfer in the C bit buffer management process.
