2.2.11 Operation of Timer A (pulse width modulation mode, 16-bit PWM mode selected)
In pulse width modulation mode, choose functions from those listed in Table 2.2.11. Operations of the
circled items are described below. Figure 2.2.24 shows the operation timing, and Figure 2.2.25 shows the
set-up procedure.
