The On-Chip Debug Support (OCDS) provides the basic functionality required for the
software development and debugging of XC800-based systems.
The OCDS design is based on these principles:
• use the built-in debug functionality of the XC800 Core
• add a minimum of hardware overhead
• provide support for most of the operations by a Monitor Program
• use standard interfaces to communicate with the Host (a Debugger)
Features:
• Set breakpoints on instruction address and within a specified address range
• Set breakpoints on internal RAM address
• Support unlimited software breakpoints in Flash/RAM code region
• Process external breaks
• Step through the program code
The OCDS functional blocks are shown in
block at the center of OCDS system brings together control signals and supports the
overall functionality. The MMC communicates with the XC800 Core, primarily via the
Debug Interface, and also receives reset and clock signals. After processing memory
address and control signals from the core, the MMC provides proper access to the
dedicated extra-memories: a Monitor ROM (holding the code) and a Monitor RAM (for
work-data and Monitor-stack). The OCDS system is accessed through the JTAG
which is an interface dedicated exclusively for testing and debugging activities and is not
normally used in an application. The dedicated MBC pin is used for external
configuration and debugging control.
Note: All the debug functionality described here can normally be used only after XC866

Data Sheet
The pins of the JTAG port can be assigned to either Port 0 (primary) or Ports 1 and 2 (secondary).
User must set the JTAG pins (TCK and TDI) as input during connection with the OCDS system.
