 - 32 Samples FIFO
 - Data Width Configurable to 24 bits, 20 bits or 16 bits
 - Packed and Unpacked Data Support for System Memory Optimization
 - Line State Events Report and Source of Interrupt
 - Line Error Rate Report
 - Full Memory Map of 192 bits for Channel 1 and Channel 2 Status and
   User Data
