CONFIDENTIAL STi5512
Diagnostic controller
The Diagnostic Controller Unit (DCU) is accessed via the JTAG test access port. It is the main access for
communication with a host for development, including loading code and debugging. It provides:
• Bootstrapping and debugging during development
• Hardware breakpoint and watchpoint facilities
• Real-time tracing
• External LSA triggering support
OS-Link serial port
The OS-Link serial port can provide communication with a host for development, including loading code and
debugging. This is provided for compatibility with previous silicon and software products.
System services module
The STi5512 system services module includes:
• A Phase Locked Loop (PLL) which accepts 27 MHz input and generates all the internal high frequency clocks
needed for the CPU and the OS-Link
• A second PLL which is used to generate all the MPEG decoder and display clocks
• A Test Access Port which is JTAG compatible
• Reset controller
