7. FUNCTIONAL DESCRIPTION
7.3
Serial Data Interface (SDI)
The serial data interface is meant for transferring compressed MPEG audio data.
Also several different tests may be activated through SDI as described in Chapter 8.
7.4
Serial Control Interface (SCI)
The serial control interface is compatible with the SPI bus specification. Data transfers are always 16-
bits. The VS1001k is controlled by writing and reading the registers of the interface.
The main controls of the control interface are:
control of the operation mode
uploading user programs
access to header data
status information
access to decoded digital data
feeding input data
