Detailed Description

Mcbsp instance Object.

Note:

This data structure holds the information pertaining to an instance of the Mcbsp device.it holds information like the current device state, handle to the McBSP channels. The data structure is initialized during "mdBindDev", which is called during DSP-BIOS initialization, and is persistent till it is invalidated by "mdUnBindDev".
