The capabilities of the 16-bit Timer/Counter type B (TCB) include frequency and waveform generation, and input capture on event with time and frequency measurement of digital signals. The TCB consists of a base counter and control logic which can be set in one of eight different modes, each mode providing unique functionality. The base counter is clocked by the peripheral clock with optional prescaling.
This device has two instances of the TCB peripheral: TCB0 and TCB1.
