3.22 SERIAL DEBUG INTERFACE
The Serial Debug Interface module (SDI module) provides a JTAG-based serial link to an external
debugger, for example running on a PC. In addition, the SDI module integrates an on-chip debug module,
which allows the user to set up to eight hardware breakpoints on instruction execution and data transfer.
The SDI module can act as a CPU bus master to access all memory mapped resources, such as RAM
and peripherals. Therefore it also allows for fast program code download into the on-chip Flash program
memory using the JTAG interface.
Note: The SDI module may assert Freeze mode to gather information, which may cause periodic
fluctuations in response (bus availability, interrupt latency, etc.). Anomalous behavior often may be traced
to SDI activity.
3.23 DEVELOPMENT SUPPORT
In addition to providing the features needed for the next generation of embedded Bluetooth products, the
CP3BT23 devices are backed up by the software resources designers need for rapid product
development, including an operating system, Bluetooth protocol stack implementation, peripheral drivers,
reference designs, and an integrated development environment. Combined with Texas Instrument’s
LMX5251 Bluetooth radio transceiver, the CP3BT23 devices provide a total Bluetooth system solution.
Texas Instruments offers a complete and industryproven application development environment for
CP3BT23 applications, including the IAR Embedded Workbench, iSYSTEM winIDEA and iC3000 Active
Emulator, Bluetooth Development Board, Bluetooth Protocol Stack, and Application Software. See your
Texas Instruments sales representative for current information on availability and features of emulation
equipment and evaluation boards.
