1 PCM InterfaceFor different digital audio subsystem, there are several interfaces between microprocessor or DSP and audio devices for digital conversion. The simplest audio interface is the PCM (Pulse coded modulation) interface, which consists of a clock pulse (BCLK), a Frame sync signal (FS), and a receive data (DR) and send data (DX). At the rising edge of th
