The asynchronous event counter (AEC) is an event counter that is incremented by external event
clock or internal clock input. Figure 13.1 shows a block diagram of the asynchronous event
counter.
13.1
• Can count asynchronous events
• Can be used as two-channel independent 8-bit event counter or single-channel independent 16-
• Event/clock input is enabled when IRQAEC goes high or event counter PWM output
• Both rising and falling edge sensing can be used for IRQAEC or event counter PWM output
• When an event counter PWM is used, event clock input enabling/disabling can be controlled at
• Selection of four clock sources
• Both rising and falling edge counting is possible for the AEVL and AEVH pins.
• Counter resetting and halting of the count-up function can be controlled by software.
• Automatic interrupt generation on detection of an event counter overflow
• Use of module standby mode enables this module to be placed in standby mode independently
Can count external events input asynchronously without regard to the operation of system

An event counter PWM can be output to the AECPWM pin.
Three internal clocks (φ/2, φ/4, or φ/8) or external event can be selected.
