Pin Definitions and Functions

Pin Description

Serial Clock (SCL)

The SCL input is used to clock data into the device on the rising edge and to clock data

out of the device on the falling edge.

Serial Data (SDA)

SDA is a bidirectional pin used to transfer addresses, data or control information into the

device or to transfer data out of the device. The output is open drain, performing a wired

AND function with any number of other open drain or open collector devices. The SDA

bus requires a pull-up resistor to
