Introduction

DM8148 processor provides a rich video subsystem - called HDVPSS - that integrates several output ports. These are described in detail on chapter 12 of Technical Reference Manual. For the sake of completeness a simplified block diagram is shown below.

Routing on Naon connectors

The following tables summarizes which signals - referred to video input/output ports - are routed to Naon connectors and thus are available to user application. It is also useful to visualize potential issues due to the pads' multiplexing scheme.
