On-Chip Debug
-
-
-
-
On-chip debug circuitry facilitates full speed, non-intrusive in-system
debug (no emulator required)
Provides breakpoints, single stepping, watchpoints
Inspect/modify memory, registers, and stack
Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Clock Sources
Internal oscillator: 24.5 MHz, 2% accuracy supports UART operation
External oscillator: Crystal, RC, C, or Clock (1 or 2 pin modes)
Can switch between clock sources on-the-fly
Supply Voltage: 2.7 to 3.6 V
