Interfaces

4.4.1

Synchronous Serial Communication (SSC)

The 3-pin SSC interface consists of a bi-directional push-pull (tri-state on receive) or open-drain data pin

(configurable with SSC_OD bit) and the serial clock and chip-select input pins. The SSC Interface is designed to

communicate with a microcontroller peer-to-peer for fast applications.

SSC Inactive Time (CSoff)

The SSC inactive time defines the delay time after a transfer before the TLE5012B can be selected again.
