7.3.2 High-Speed Time Base Counter
The high-speed time base counter is configured as a 4-bit 1/n counter (n = 1 to 16).
In the 4-bit 1/n counter, the divided clock (1/16 x HSCLK to 1/1 x HSCLK) selected by the high-speed time base
counter divide register (HTBDR) is generated as HTBCLK. HTBCLK is used as a timer and also as an operation clock
of PWM.
Figure 7-5 shows the output waveform of HTBCLK.
