6.3 PCM Manager in DSP Composer
All configuration information described in Section 6.2 can be controlled in DSP Composer. Note that IO Buffer Channel
availability is device specific. The PCM Manager is part of the System block. To insert System block, drag in onto the
workspace. Once the System block is on the workspace the runtime and pre-kick controls for the PCM Manager can be
accessed by double-clicking the System block. When the System Block is first dragged onto the workspace the user is
prompted to select device and input mode as seen in
Fig. 6-1 . These settings can also be accessed by right-clicking the
System block and selecting Device Properties.
