FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

Figure 8. Single 16-Bit Word SPI Communication

SERIAL INPUT (SI)

The SI pin is a serial interface command data input pin.

Each SI bit is read on the falling edge of SCLK. A 16-bit

stream of serial data is required on the SI pin, starting with

D15 to D0. SI has a passive pull-down, RDOWN.

SERIAL OUTPUT (SO)

The SO data pin is a tri-stateable output from the shift

the CS pin is put into a logic [0] state. The SO data is capable

of reporting the status of the output, the device configuration,

and the state of the key inputs. The SO pin changes state on

the rising edge of SCLK and reads out on the falling edge of

SCLK.

CHIP SELECT (CS)

The CS pin enables communication with the master

device. When this pin is in a logic [0] state, the device is

capable of transferring information to, and receiving

information from, the master device. The 10XS3535 device

latches in data from the Input Shift registers to the addressed

registers on the rising edge of CS. The device transfers

status information from the power output to the Shift register

on the falling edge of CS. The SO output driver is enabled

when CS is logic [0]. CS should transition from a logic [1] to a

logic [0] state only when SCLK is a logic [0]. CS has a

passive pull-up, RUP.

RSTB is in a logic H state during the above operation.

DO, D1, D2, ... , and D15 relate to the most recent ordered entry of program data into the LUX IC

OD0, OD1, OD2, ..., and OD15 relate to the first 16 bits of ordered fault and status data out of the LUX IC
