24.1 Module Introduction
The Data Converter Interface (DCI) module allows
simple interfacing of devices, such as audio coder/
decoders (Codecs), ADC and D/A Converters. The
following interfaces are supported:
• Framed Synchronous Serial Transfer (Single or
Multi-Channel)
• Inter-IC Sound (I²S) Interface
• AC-Link Compliant mode
General features include:
• Programmable word size up to 16 bits
• Supports up to 16 time slots, for a maximum
frame size of 256 bits
• Data buffering for up to 4 samples without CPU
overhead
