C515C + PWM

Hi every body, and happy new year to all keil users ;)
I am using the C515C with keil v2.39,
I want to generate a PWM signal using one of the pins 1.0,1.1,1.2 or 1.3,
I read the manual, put I found it difficult, because I have to configure different things.
Like the following parameters:

T2CON |= 0x10; ET2=1; EXEN2=0; CRCL = 0x22; CRCH = 0xFF; EX3=0; CCL1 = 0xFF; CCH1 = 0x22; EX4=0; CCL2 = 0x00; CCH2 = 0x00; EX5=0; CCL3 = 0x000; CCH3 = 0x000; EX6=0; CCEN = 0xAA;

What I know, is that we have to use compare mode 0.

But how can I set T2 to be ready for all things, and how I change the duty cycle while from the program results...

Is there any ready function that has one input which is the duty cycle?

And thank you for your time.
