User manual

The I2S protocol
▶
Used by CODEC chips in the C5515 and the DE2-70 for data transfer.
▶
Several modes of operation, stereo, mono, etc.
▶
When C5515 is a master the word rate is fixed and constant. When
C5515 is slave the edge timings from the FPGA rule!
▶
A reasonable use is an reverse channel from FPGA to C5515.
▶
A useful reference is the C5515 I2S User’s guide, SPRUFX4.
