MSP430F427: PWM Generate on MSP430F427

Hawa Singh Yadav

Part Number: MSP430F427

I want to generate PWM(100%,50%,25%,20% etc) on PIN NO. 53 i.e. P1.0(TA0) in MSP430F427 MCU

Please tell me how to generate PWM on this PIN

    TA0 (CCR0) can't be used for "real" hardware PWM. It can provide 50% duty but that's it. This is what the User Guide means by "Output modes 2, 3, 6, and 7 are not useful for output unit 0, because EQUx = EQU0." [Ref UG (SLAU056L) Sec 15.2.5, second paragraph]

    If you're stuck with using that pin, I expect you'll need to do software PWM. There's a Reference Design which describes the technique and has some sample code. It's for the G2553, but that has the same TimerA unit:
