Input 0 & Input 1
Input 2 & Input 3
Input 4 & Input 5
These input terminals control two output channels each when the
MODE
terminal is
pulled high. These terminals may be connected to pulse width modulated (PWM)
outputs of the control IC while the
MODE
terminal is high. The states of these terminals
are ignored during normal operation (
MODE
terminal low) and override the normal
inputs (serial or parallel) when the
MODE
terminal is high. These terminals have
internal active 25
μ
A pull-downs.

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

SI
Serial Input
The Serial Input terminal is connected to the SPI Serial Data Output terminal of the
control IC from where it receives output command data. This input has an internal
active 25
μ
A pull-down and requires CMOS logic levels.
13
SCLK
Serial Clock
The SCLK terminal of the control IC is a bit (shift) clock for the SPI port. It transitions
one time per bit transferred when in operation. It is idle between command transfers. It
is 50% duty cycle, and has CMOS levels.
14
CS
Chip Select
This terminal is connected to a chip select output of the control IC. This input has an
internal active 25
μ
A pull-up and requires CMOS logic levels.
