MSP430FR5969: PWM on P2.4

Part Number: MSP430FR5969

Hi,

I have attached the code I usually use to setup a PWM output. I don't understand if is possible set P2.4 (TA1.0) as a PWM output, because TA1CCCR0 is used to set the PWM period. Maybe there is a different way to set P2.4, P1.2 and P1.3 as PWM output.

Thanks

Riccardo

//Timer A1 : PWM

TA1CTL = TASSEL__SMCLK |ID__1| MC__UP | TACLR;           // SMCLK, up mode, clear TAR
TA1EX0 = TAIDEX_7;                                                                 // DIV1 : So timer_CLK = SMCLK/1
TA1CCR0 =  2000;                                                                     // PWM Period 1 kHz
TA1CCTL1 = OUTMOD_7;                                                         // P1.2 : CCR1 reset/set
TA1CCR1 =  0;                                                                           // P1.2 : CCR1 PWM duty cycle (PWM MOTOR)
TA1CCTL2 = OUTMOD_7;                                                         // P1.3 : CCR2 reset/set
TA1CCR2 =  0;                                                                           // P1.3 : CCR2 PWM duty cycle (PWM FAN 24V)

    You can use any CCR except CCR0 for PWM output.

    P2.4 uses CCR0, so it cannot be used for PWM output.

    If you really cannot change the pins, you have to toggle the pin in software.
