Step2: Set PWM Mode
This setting includes two modes – "Burst Count Mode" and "Continous Mode".
"Burst Count Mode" means it can output mutiple fixed pluse in a period time
and then stop output. "Continous Mode" means it can output one fixed pluse in
a period time and continue output.
In this example, we enter "1" to set it as "Continous mode".
API : Refer to section 3.9
Step3: Set PWM Duty
There are three options in this setting, if you choose:
 "0" means you can enter an integer value (ex. input 50 to set it as 50%) 
 "1" means you can enter an integer value to set it as one decimal place
value. (ex. input 999 to set it as 99.9%)
 "2" means you can enter a one decimal place value. (ex. input 99.9 to set it
as 99.9%)

In this example, please enter "0" to set it as "Normal integer Duty"
