IIS-BUS INTERFACE
OVERVIEW
Many digital audio systems are introduced into the consumer audio market, including compact disc, digital audio
tapes, digital sound processors, and digital TV sound. The S3C2400 IIS (Inter-IC Sound) bus interface can be used
to implement a CODEC interface to an external 8/16-bit stereo audio CODEC IC for mini-disc and portable
applications. It supports the IIS bus data format and MSB-justified data format. IIS bus interface provides DMA
transfer mode for FIFO access instead of an interrupt. It can transmit or receive data simultaneously as well as
transmit or receive only.
FEATURES
— IIS, MSB-justified format compatible
— 8/16-bit data per channel
— 16, 32, 48fs (sampling frequency) serial bit clock per channel
— 256, 384fs master clock
— Programmable frequency divider for master clock and CODEC clock
— 32 bytes (2 16) FIFO for transmit and receive
— Normal and DMA transfer mode
