IC while the MODE pin is high. The states of these pins are ignored during normal
operation (MODE pin low) and override the normal inputs (serial or parallel) when the
MODE pin is high. These pins have internal active 25 µA pull-downs.

Mode Select
The MODE pin is connected to the MODE pin of the control IC. This pin has an internal
active 25 µA pull-up.

Serial Input
The Serial Input pin is connected to the SPI Serial Data Output pin of the control IC
from where it receives output command data. This input has an internal active 25 µA
pull-down and requires CMOS logic levels.
