Duty cycle mapping refer to following table.
0000: 0x6.25% = 0% duty cycle
0001: 5x6.25% = 31.25% duty cycle
0010: 5x6.25% = 31.25% duty cycle
0011: 5x6.25% = 31.25% duty cycle
0100: 5x6.25% = 31.25% duty cycle
1000: 9x6.25% = 56.25% duty cycle
1001: 10x6.25% = 62.50% duty cycle
1010: 11x6.25% = 68.75% duty cycle
1011: 12x6.25% = 75.00% duty cycle
1100: 13x6.25% = 81.25% duty cycle
