Development Support
12.1
Development support systems in the RS08 family include the RS08 background debug controller (BDC).
The BDC provides a single-wire debug interface to the target MCU. This interface provides a convenient
means for programming the on-chip FLASH and other nonvolatile memories. Also, the BDC is the
primary debug interface for development and allows non-intrusive access to memory data and traditional
debug features such as CPU register modify, breakpoint, and single-instruction trace commands.
In the RS08 Family, address and data bus signals are not available on external pins. Debug is done through
commands fed into the target MCU via the single-wire background debug interface, including resetting the
device without using a reset pin.

Uses a single pin for background debug serial communications
Non-intrusive of user memory resources; BDC registers are not located in the memory map
SYNC command to determine target communications rate
Non-intrusive commands allow access to memory resources while CPU is running user code
without stopping applications
Active background mode commands for CPU register access
GO and TRACE1 commands
BACKGROUND command can wake CPU from wait or stop modes
