CC2640 how to use two pwm with timerA

Hi TI engineer,

I want to use three pwm in my projuct,blow is my code ,GTP0 IS ok. But GPT1 can not work. I would like to know how to configure GPT1,thank you.

void taskFxn(UArg a0, UArg a1)
{
 
    // Register client for pins in pwmExamplePins array
    pinHandle = PIN_open(&pinState, pwmExamplePins);
    // Route LED1 pin on SmartRF06EB to IO event port 0 (0 = Timer0A, 1 = Timer0B, 2 = Timer1A..)
    PINCC26XX_setMux(pinHandle, PIN_ID(Board_PitchA), IOC_PORT_MCU_PORT_EVENT0);
    PINCC26XX_setMux(pinHandle, PIN_ID(Board_PitchB), IOC_PORT_MCU_PORT_EVENT1);
 
    PIN_registerIntCb(pinHandle, pinCallBack);
 
    // Turn on PERIPH power domain and clock for GPT0
    Power_setDependency(PERIPH_GPT0);
    Power_setDependency(PERIPH_GPT1);
 
//   timerInitialize();
    TimerConfigure(GPT0_BASE, TIMER_CFG_SPLIT_PAIR|TIMER_CFG_A_PWM);
    TimerLoadSet(GPT0_BASE, TIMER_A, TIMER_LOADSET);
    TimerMatchSet(GPT0_BASE, TIMER_A, TIMER_MATCH);
 
    TimerConfigure(GPT1_BASE, TIMER_CFG_SPLIT_PAIR|TIMER_CFG_A_PWM);
    TimerLoadSet(GPT1_BASE, TIMER_A, TIMER_LOADSET);
    TimerMatchSet(GPT1_BASE, TIMER_A, TIMER_MATCH);
 
    TimerEnable(GPT0_BASE, TIMER_A);
    TimerEnable(GPT1_BASE, TIMER_A);
 
 
 
    while(1)
    {
 
 
 
    }
}
