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