TIMER_PERIOD

#define TIMER_PERIOD   511

This program generates two PWM outputs on P1.2,P1.3 using Timer1_A configured for up mode. The value in CCR0, 512-1, defines the PWM period and the values in CCR1 and CCR2 the PWM duty cycles. Using ~1.045MHz SMCLK as TACLK, the timer period is ~500us with a 75% duty cycle on P2.2 and 25% on P2.3. ACLK = n/a, SMCLK = MCLK = TACLK = default DCO ~1.045MHz.

Tested On: MSP430FR5749

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 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
