setPWM(servo_number,tick_on,tick_off) -- 1 cycle = 4096 ticks

time length of 1 cycle determined by frequency - e.g. 1000Hz -> 1 cycle = 1ms, split into 4096 ticks.
For ease of calcuation, Freq = 48.828125Hz, means 1 cycle = 20.48ms, and 1 tick length = 5us:

      MIN MAX

ticks 100 500
deg   0   180
