Prior to Timer_A3 setup, CC channels are setup. OUTMOD is that stuff that sets PWM type.
/*
* TA0CCTL0, Capture/Compare Control Register 0
*
* CM_0 -- No Capture
* CCIS_0 -- CCIxA
* ~SCS -- Asynchronous Capture
* ~SCCI -- Latched capture signal (read)
* ~CAP -- Compare mode
* OUTMOD_4 -- PWM output mode: 4 - Toggle
*
* Note: ~<BIT> indicates that <BIT> has value zero
*/
TA0CCTL0 = CM_0 | CCIS_0 | OUTMOD_4;
/*
* TA0CCTL1, Capture/Compare Control Register 1

* CM_0 -- No Capture
* CCIS_0 -- CCIxA
* ~SCS -- Asynchronous Capture
* ~SCCI -- Latched capture signal (read)

TA0CCTL1 = CM_0 | CCIS_0 | OUTMOD_3;
/*
* TA0CCTL2, Capture/Compare Control Register 2
*
* CM_0 -- No Capture
* CCIS_0 -- CCIxA
* ~SCS -- Asynchronous Capture
* ~SCCI -- Latched capture signal (read)

*/
TA0CCTL2 = CM_0 | CCIS_0 | OUTMOD_7;
In this demo, three different PWMs are set to show the differences.
