31. TCC – Timer/Counter for Control Applications
31.1 Overview
The device provides three instances of the Timer/Counter for Control applications (TCC) peripheral,
TCC[2:0].
Each TCC instance consists of a counter, a prescaler, compare/capture channels and control logic. The
counter can be set to count events or clock pulses. The counter together with the compare/capture
channels can be configured to time stamp input events, allowing capture of frequency and pulse-width. It
can also perform waveform generation such as frequency generation and pulse-width modulation.
Waveform extensions are featured for motor control, ballast, LED, H-bridge, power converters, and other
types of power control applications. They allow for low- and high-side output with optional dead-time
insertion. Waveform extensions can also generate a synchronized bit pattern across the waveform output
pins. The fault options enable fault protection for safe and deterministic handling, disabling and/or shut
down of external drivers.
Figure 31-1 shows all features in TCC.
Note: The TCC configurations, such as channel numbers and features, may be reduced for some of the
TCC instances.
