BITA
Brightness Control Input (Multimode):
DPWM Mode: DPWM control signal input.
Analog Mode: Connect to IN.
2- or 3-Bit Parallel Mode: Digital input. Most significant bit (MSB).
Brightness Control Input:
DPWM Mode: Connect to IN.
Analog Mode: Connect to IN.
2-Bit Parallel Mode: Connect to GND.

MODE
Brightness Control Mode Selection Input. Connect MODE and BITC to IN for
DPWM control. Connect MODE, BITA, and BITC to IN for analog control. For 2-bit
parallel control, connect MODE to IN and BITC to ground. For 3-bit parallel control,
connect MODE to GND.
LED Selection Input. Connect SEL to IN to turn on all LEDs. Connect SEL to ground
to turn on only LED1
LED5 (MAX1984), LED1
LED4 (MAX1985), or LED1 to LED3
(MAX1986). Leave SEL unconnected or force to V
IN
/2 to turn on only LED6 to LED8
(MAX1984), LED3
LED6 (MAX1985), or LED4 (MAX1986).
