VDD Monitor and Brown-out Detector
On-Chip JTAG Debug
- On-chip emulation circuitry facilitates full-speed, non-intrusive, in-circuit
emulation
- Supports breakpoints, single stepping, watchpoints, inspect/modify
memory, and registers
- Superior performance to emulation systems using ICE-chips, target
pods, and sockets
