Specifications
3.5
Interfaces
Within the register MOD_3, the driver strength and so the slope for push-pull communication can be varied with
the sensor output. The driver strength is specified in Table 3 and the slope fall and rise times in Table 12.

3.5.1 Synchronous Serial Communication (SSC) Interface
The 3-pin SSC Interface has a bi-directional push-pull data line, serial clock signal, and chip select. The SSC
Interface is designed to communicate with a microcontroller peer-to-peer for fast applications.
