PRODUCTION DATA.
With BRT_MODE = 11, the PWM control signal path is similar to the path when BRT_MODE = 01 except that the PWM input signal is multiplied with BRT[7:0] data after the Curve-Shaper block.
PWM_DIRECT | BRT_MODE [1:0] | BRIGHTNESS CONTROL SOURCE | OUTPUT ILED FORM | |
---|---|---|---|---|
0 | 00 | External PWM signal | Adaptive. See Output Dimming Schemes | |
0 | 01 | External PWM signal and Brightness Register
(multiplied before Curve Shaper) |
||
0 | 10 | Brightness Register | ||
0 | 11 | External PWM signal and Brightness Register
(multiplied after Curve Shaper) |
||
1 | don't care | External PWM signal | Same as the external PWM input |
