Section 13 Asynchronous Event Counter (AEC)
Figure 13.4 and table 13.2 show examples of event counter PWM operation.
Note: Ndr and Ncm above must be set so that Ndr < Ncm. If the settings do not satisfy this
Table 13.2 Examples of Event Counter PWM Operation
Conditions:
active mode, ECPWCR value (Ncm) = H'7A11, ECPWDR value (Ndr) = H'16E3
