This LSI includes 4 channels of 8-bit timers.
For input clocks, see Chapter 6, “Clock Generation Circuit”.
Figure 9-1 shows the configuration of the timers.

• A timer configured by combining timer 0 and timer 1 or timer 2 and timer 3 can be used as a 16-bit timer.
• For the timer clock, the low-speed clock (LSCLK), high-speed time base clock (HTBCLK), or external clock can
