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.

ger. The in-circuit debug features include the following:
• A hardware debug engine
• A set of registers able to set breakpoints on register,
• A set of debug service routines stored in the utility ROM
The embedded hardware debug engine is an independ-
ent 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 fea-
tures allow two basic modes of in-circuit debugging:
• Background mode allows the host to configure and
• Debug mode allows the debug engine to take control

To achieve the best results when using the DS4830,
decouple the V
tor. Use a high-quality, ceramic, surface-mount capaci-
tor if possible. Surface-mount components minimize
lead inductance, which improves performance, and
ceramic capacitors tend to have adequate high-frequen-
cy response for decoupling applications.Decouple the
REG285 and REG18 pins using 1FF and 10nF capacitors
(one each/per output). Note: Do not use either of these
pins for external circuitry.
