47.6.2.6 Compare Operations

By default, the Compare/Capture channel is configured for compare operations. To perform capture operations, it must be re-configured.

When using the TCC with the Compare/Capture Value registers (CCy) for compare operations, the counter value is continuously compared to the values in the CCy registers. This can be used for timer or for waveform operation.

The Channel y Compare/Capture Buffer Value (CCBUFy) registers provide double buffer capability. The double buffering synchronizes the update of the CCy register with the buffer value at the UPDATE condition or a force update command (CTRLBSET.CMD (CTRLBSET <5:3>)=0x3, UPDATE). For further details, refer to Double Buffering. The synchronization prevents the occurrence of odd-length, non-symmetrical pulses and ensures glitch-free output.
