PWM source mode
00b = PWM input pin duty cycle control (default)
01b = PWM input pin duty cycle control
10b = Brightness register
11b = Direct PWM control from PWM input pin
BL_CTL

R/W
Enable backlight
0 = Backlight disabled and chip turned off if BRT_MODE[1:0] = 10. In external PWM
pin control the state of the chip is defined with the PWM pin and this bit has no
effect.
1 = Backlight enabled and chip turned on if BRT_MODE[1:0] = 10. In external PWM
pin control the state of the chip is defined with the PWM pin and this bit has no
effect.
