I_SLOPE[2:0] |
7:5 |
R/W |
Slope gain adjusts the current slope for Hybrid PWM and Current dimming mode
000 = 1.000
001 = 1.023
010 = 1.047
011 = 1.070
100 = 1.094
101 = 1.117
110 = 1.141
111 = 1.164 |
PWM_RESOLUTION[1:0] |
4:3 |
R/W |
For PWM clocking with internal oscillator (VSYNC is not used) these bits control the PLL multiplier and hence the PWM output resolution
00 = 5-MHz clock used for generating PWM
01 = 10-MHz clock used for generating PWM
10 = 20-MHz clock used for generating PWM
11 = 40-MHz clock used for generating PWM |
DITHER[2:0] |
2:0 |
R/W |
Dither function controls
000 = Dither function disabled
001 = 1-bit dither
010 = 2-bit dither
011 = 3-bit dither
1XX = 4-bit dither |
