Section 9 Timers
Clock Input Enable/Disable Function Operation
The clock input to the event counter can be controlled by the IRQAEC pin when ECPWME in
AEGSR is 0, and by event counter PWM output IECPWM when ECPWME in AEGSR is 1. As
this function forcibly terminates the clock input by each signal, a maximum error of one count will
occur depending the IRQAEC or IECPWM timing.
Figure 9.23 shows an example of the operation of this function.
