Synopsis
Port Number: B024
Function: Backlight PWM level
This port controls the backlight PWM dimming level. 00 is full PWM duty cycle, FF is minimum duty cycle. Setting this above TI's maximum of E5 may or may not be bad for the backlight LEDs. (Recall that high-power LEDs are driven with constant-current PWM drivers instead of loading resistors.)
