In-Circuit Debug
Embedded debugging capability is available through
the JTAG-compatible test access port (TAP). Embedded
debug hardware and embedded ROM firmware provide
in-circuit debugging capability to the user application,
eliminating the need for an expensive in-circuit emulator.
Figure 6 shows a block diagram of the in-circuit debug-
ger. The in-circuit debug features include the following:
Hardwaredebugengine
Set of registers able to set breakpoints on register,
code, or data accesses (ICDA, ICDB, ICDC, ICDD,
ICDF, ICDT0, and ICDT1)

The embedded hardware debug engine is an indepen-
dent hardware block in the microcontroller. The debug
engine can monitor internal activities and interact with
selected internal registers while the CPU is executing
user code. Collectively, the hardware and software
features allow two basic modes of in-circuit debugging:
background and debug.
Background mode allows the host to configure and set
up the in-circuit debugger while the CPU continues to
execute the application software at full speed. Debug
mode can be invoked from background mode.
Debug mode allows the debug engine to take control of
the CPU, providing read/write access to internal regis-
ters and memory, and single-step trace operation.
Applications Information
Power-Supply Decoupling
To achieve the best results when using the device,
decouple the VDD power supply with a 0.1FF capacitor.
Use a high-quality, ceramic, surface-mount capacitor
if possible. Surface-mount components minimize lead
inductance, which improves performance, and ceram-
ic capacitors tend to have adequate high-frequency
response for decoupling applications.
Decouple REG25 and REG18 using 1FF and 10nF
capacitors (one each per output). Note: Do not use
either of these pins for external circuitry.
