CC1312R: How to generate two different PWMs from same timer channels?

Dear Sir,

I am using Timer 3, channel a to generate pwm. Now, i am trying to use channel b to generate another PWM which has different frequency. Looks like it generates PWM using Ch a but Ch b is not generating PWM.

The PWM init code is below.

void Init_pwm(void)
{
PWM_init();

PWM_Params_init(&pwmParams);
PWM_Params_init(&beeperPWMParams);

pwmParams.idleLevel = PWM_IDLE_LOW; // Output low when PWM is not running
pwmParams.periodUnits = PWM_PERIOD_US; // Period in microseconds
pwmParams.periodValue = 333333;//1e6; // change this to 100hz the minimum freq can be set is 3hz
pwmParams.dutyUnits = PWM_DUTY_FRACTION; // Duty is in fractional percentage
pwmParams.dutyValue = 50; // 0% initial duty cycle

beeperPWMParams.idleLevel = PWM_IDLE_LOW; // Output low when PWM is not running
beeperPWMParams.periodUnits = PWM_PERIOD_US; // Period in microseconds
beeperPWMParams.periodValue = 200;//1e6; // 1MHz change this to 100hz the minimum freq can be set is 3hz
beeperPWMParams.dutyUnits = PWM_DUTY_FRACTION; // Duty is in fractional percentage
beeperPWMParams.dutyValue = 50; // 0% initial duty cycle

pwm = PWM_open(DRV_CLKIN_PWM, &pwmParams);

beeperPWM = PWM_open(BEEPER_PWM, &beeperPWMParams);

if ((pwm == NULL)||(beeperPWM==NULL))
{
// PWM_open() failed
SubgConPrint("Failed to open PWM Timer\r\n"); //print error
}

PWM_start(beeperPWM);
}

PWM Config is below.

#define CONFIG_PWM_COUNT 2

/*
* ======== pwmCC26XXObjects ========
*/
PWMTimerCC26XX_Object pwmTimerCC26XXObjects[CONFIG_PWM_COUNT];

/*
* ======== pwmCC26XXHWAttrs ========
*/
const PWMTimerCC26XX_HwAttrs pwmTimerCC26XXHWAttrs[CONFIG_PWM_COUNT] = {
/* DRV_CLKIN_PWM */
{
.pwmPin = IOID_25,
.gpTimerUnit = CONFIG_GPTIMER_0
},
/* BEEPER_PWM */
{
.pwmPin = IOID_16,
.gpTimerUnit = CONFIG_GPTIMER_4
},
};

/*

*/
const PWM_Config PWM_config[CONFIG_PWM_COUNT] = {
/* DRV_CLKIN_PWM */
{
.fxnTablePtr = &PWMTimerCC26XX_fxnTable,
.object = &pwmTimerCC26XXObjects[DRV_CLKIN_PWM],
.hwAttrs = &pwmTimerCC26XXHWAttrs[DRV_CLKIN_PWM]
},

};

Please guide me to make it work.
