The number of data nibbles per message can be configured betweenandThe basic SENT protocol tick length, which defaults tomicroseconds, can be varied on the flyThis application note describes the SENT/SPC driver for the MPC bit family of microcontrollers. The Single-Edge Nibble Transmission (SENT) protocol transports highresolution sensor data for temperature, pressure, throttle position, and mass airflow in automotive This document defines a level of standardization in the implementation of the digital pulse scheme for reporting sensor information via Single Edge Nibble Transmission (SENT) The demo driver can configure all the channels for each SENT instance. The basic unit of time in SENT is called a tick, where a tick can be Key Features The SENT protocol is a one-way, asynchronous voltage interface which requires three wires: a signal line (low stateV), a supply voltage line (5 V) and a ground line. SENT. SENT uses pulse-width modulation to encode four bits (one nibble) per symbol. SENT is a point to point protocol, operating between a sensor and an Electronic Control Unit (ECU) The sensor emits data continuously over the link while the ECU receives and processes the data.
