9. Functional Timer
9.1 General Description
The Functional timer enables following functions in four operation modes (TIMER/CAPTURE/PWM1/PWM2).
TIMER mode:
In this mode, the MCU generates pulse signals reversed every timer cycle, changing the timer output level in
syncroniztion with the count start or the over flow of the counter. Also, it generates the interrupt when the counter
overflows.
CAPTURE mode:
In this mode, the MCU stores the value of counter into FTnEA register at the rising edge of a trigger event, into FTnEB
register at the falling edge of a trigger event.
PWM1 mode:
In this mode, the MCU generates two types of PWM waveform that have the same cycle and the start timing.
The setting value of FTnEA register makes the duty of FTMnP pin output signal and the setting value of FTnEB
register makes the duty of FTMnN pin output signal.
PWM2 mode:
In this mode, the MCU generates the complimentary PWM waveform of which the FTMnP pin output and the FTMnN
pin output works exclusively. The setting of FTnEA register makes the duty of the FTMnP pin output.
Also, a deadtime can be configured by setting FTMnDT reigister.
