1.3 Embedded Emulation
Dedicated embedded emulation logic resides on the device itself and is
accessed via JTAG using no additional system resources.
The benefits of embedded emulation include:
- Unobtrusive development and debug with full-speed execution,
breakpoints, and single-steps in an application are supported.
- Development is in-system subject to the same characteristics as the final
application.
- Mixed-signal integrity is preserved and not subject to cabling interference.
