TIMER_A_PERIOD

#define TIMER_A_PERIOD   250

Toggle P2.4 using hardware TA1.0 output. Timer1_A is configured for up/down mode with CCR0 defining period, TA1.0 also output on P2.4. In this example, CCR0 is loaded with 250 and TA1.0 will toggle P2.4 at TACLK/2*250. Thus the output frequency on P2.4 will be the TACLK/1000. No CPU or software resources required. As coded with TACLK = SMCLK, P2.4 output frequency is ~1.045M/1000. SMCLK = MCLK = TACLK = default DCO ~1.045MHz

Tested On: MSP430FR5969

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
