10 ------------
12 Every audio subsystem is driven by a master clock (sometimes referred to as MCLK
13 or SYSCLK). This audio master clock can be derived from a number of sources
14 (e.g. crystal, PLL, CPU clock) and is responsible for producing the correct
17 Some master clocks (e.g. PLLs and CPU based clocks) are configurable in that
19 power). Other master clocks are fixed at a set frequency (i.e. crystals).
23 ----------
24 The Digital Audio Interface is usually driven by a Bit Clock (often referred to
25 as BCLK). This clock is used to drive the digital audio data across the link
