Square wave generate 1Hz to 40Hz with different PWM duty cycle

I am using CC2650. I am facing problem with TIMER. I want to generate 1 Hz to 40 Hz signal in two separate pins and change PWM signal with certain period of time.

Example:

TIME | PIN0 Freq. | PIN0 PWM | PIN1 Freq. | PIN1PWM | Alternate Mode 
T0      |       2Hz       |        50%     |         2Hz     |     50%       |     0 
T1      |       3Hz       |        50%     |       15Hz     |     20%       |     0 
T2      |      30.5Hz  |        40%      |     2.5Hz     |      50%      |     0  
T3      |      2Hz       |         50%      |       2Hz      |       50%     |     1

* Alternate Mode activate gives 180 degree phase shift b/w PIN0 and PIN1

* i have to change all the frequency by giving  the data on UART apps 

#i am very new with  CC2650 . please help me .
