Serial Input (SI)
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, R
Serial Output (SO)
The SO pin remains in a high-impedance state until 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.

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 35XS3500 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

component is active in case of a logic high at the input.
