R/W 0h
Reduce the divide factor by 1. Applicable for all divide ratios of
6 and above (not applicable for divide ratio of 4)
If apb_clk_divide_factor = 2, and apb_clk_div_factor_odd=1,
the the divide ratio is 5
If apb_clk_divide_factor = 4, and apb_clk_div_factor_odd=1,
the the divide ratio is 7
If apb_clk_divide_factor = 8, and apb_clk_div_factor_odd=1,
the the divide ratio is 9
If apb_clk_divide_factor = 16, and apb_clk_div_factor_odd=1,
the the divide ratio is 11
If apb_clk_divide_factor = 32, and apb_clk_div_factor_odd=1,
the the divide ratio is 13
If apb_clk_divide_factor = 0, and apb_clk_div_factor_odd=1,
the the divide ratio is 15
When dithering is enabled (setting cfg_dithered_mode_en=1),
the divide factor will dynamically change between N and N-1
(one lower than the above mentioned divide factors).
If apb_clk_div_factor = 1, and apb_clk_div_factor_odd=1/0,
the the divide ratio is (3,4)
If apb_clk_div_factor = 2, and apb_clk_div_factor_odd=1, the
the divide ratio is (4,5)
If apb_clk_div_factor = 2, and apb_clk_div_factor_odd=0, the
the divide ratio is (5,6)
If apb_clk_div_factor = 4, and apb_clk_div_factor_odd=1, the
the divide ratio is (6,7)
If apb_clk_div_factor = 4, and apb_clk_div_factor_odd=0, the
the divide ratio is (7,8)
If apb_clk_div_factor = 8, and apb_clk_div_factor_odd=1, the
the divide ratio is (8,9)
If apb_clk_div_factor = 8, and apb_clk_div_factor_odd=0, the
the divide ratio is (9,10)
If apb_clk_div_factor = 16, and apb_clk_div_factor_odd=1, the
the divide ratio is (10,11)
If apb_clk_div_factor = 16, and apb_clk_div_factor_odd=0, the
the divide ratio is (11,12)
If apb_clk_div_factor = 32, and apb_clk_div_factor_odd=1, the
the divide ratio is (12,13)
If apb_clk_div_factor = 32, and apb_clk_div_factor_odd=0, the
the divide ratio is (13,14)
If apb_clk_div_factor = 0, and apb_clk_div_factor_odd=1, the
the divide ratio is (14,15)
If apb_clk_div_factor = 0, and apb_clk_div_factor_odd=0, the
the divide ratio is (15,16)
If apb_clk_divide_factor = 0, and apb_clk_div_factor_odd=1,
the the divide ratio is 15
