40.6.4 Host/Client Operation

Two TCC (TCC0 and TCC1) instances sharing the same GCLK_TCC clock, can be linked to provide more synchronized CC channels. The operation is enabled by setting the Host Synchronization bit in Control A register (CTRLA.MSYNC) in the Client instance (TCC1). When the bit is set, the client TCC instance will synchronize the CC channels to the Host counter (TCC0).
