no external clock

> Programmable clock frequency with 1024

options ranging from divide by 16 to multiply

by 64 from base oscillator

> Real-time interrupt

> Watchdog

> Reliable, robust operation

> Provides high performance using low-cost

reference crystals

> Reduces generated noise

> Reduces power consumption

> Easily able to implement real-time clock

Enhanced Capture Timer

> 8-channel, 16-bit with input capture, output

compare and pulse accumulator

> 16-bit modulus down counter

> Flexible, programmable timer system

8-bit or 16-bit Pulse-Wide Modulation (PWM)
