6.2 PCM Manager in DSP Composer

All configuration information described in Section 6.1 can be controlled in DSP Composer. I/O buffer channel availability

is device specific. The PCM Manager is part of the System block. To insert a System block, drag it onto the workspace.

When 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.

The runtime controls are accessed by double-clicking the System Block as shown in Fig. 6-2.
