Timer_A3, PWM TA1.1-2, Up/Down Mode, DCO SMCLK

Description: This program generates two PWM outputs on P2.0,P2.1 using Timer1_A configured for up/down mode. The value in CCR0, 128, defines the PWM period/2 and the values in CCR1 and CCR2 the PWM duty cycles. Using ~1.045MHz SMCLK as TACLK, the timer period is ~233us with a 75% duty cycle on P2.0 and 25% on P2.1. SMCLK = MCLK = TACLK = default DCO ~1.045MHz.

Tested On: MSP430F5529

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• Timer peripheral
• GPIO Port peripheral

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• NONE
