frequency 24Hz) ，0xFF = (10.73s)，Frequency = [(0~255) + 1]/24=
x(second) ，Ex：300ms = (7 + 1) / 24 ≒ 0.333s。
Remarks: This structure has used to store the blinking duty cycle and frequency of LED IC.
Please attention one LED IC only has one duty cycle and frequency to be group
used, It means all LED has the same blink mode on a LED IC.
