Input

Serial Input Data

The SI input pin is used to receive serial data from the MCU. The serial

input data is latched on the rising edge of SCLK, and the input data

transitions on the falling edge of SCLK.

10

SCLK

Input

Serial Clock Input

The SCLK input pin is used to clock in and out the serial data on the SI

and SO Pins while being addressed by the CS.

11

CS

Input

Chip Select

The Chip Select input pin is an active low signal sent by the MCU to

indicate that the device is being addressed. This input requires CMOS

logic levels and has an internal active pull up current source.

12

P1

Input

Input One

Input control of OSS output 1. When configured via the SPI, P1 input may

be used to control OSS output 1 and output 2 in parallel.

13

P3

Input

Input Three

Input control of OSS output 3. When configured via the SPI, P3 input may

be used to control OSS output 3 and output 4 in parallel.

14

P5

Input

Input Five

Input control of OSS output 5. When configured via the SPI, P5 input may

be used to control OSS output 5 and output 6 in parallel.
