On-Chip Debug
-
-
-
-
On-chip debug circuitry facilitates full speed, non-
intrusive in-system debug (no emulator required)
Provides breakpoints, single stepping,
inspect/modify memory and registers
Superior performance to emulation systems using
ICE-chips, target pods, and sockets
-
-
Four general purpose 16-bit counter/timers
16-Bit programmable counter array (PCA) with three
capture/compare modules and enhanced PWM
functionality
-
Real time clock mode using timer and crystal
Clock Sources
-
Low cost, complete development kit
24.5 MHz ±2% Oscillator
Supply Voltage 2.7 to 3.6 V
Built-in voltage supply monitor
