E9000SPC
This example shows how to handle the TLE5012B-E9000 variant with SPC interface Author Infineon Technologies AG Copyright 2020 Infineon Technologies AG Version 3.1.0 The TLE5012B-E9000 with SPC interface does not start the DSP automatically in a loop at start up. It will need a certain trigger on the IFA pin of the sensor. This trigger must be in a 90 UT time frame at least 12 UT long for the first sensor. By multiplying the 12 UT with the sensor slave number up to four sensors can be triggered. This trigger setting UT the unittime must multiplied with the sensors base unittime which is default 3.0µs. Setting the IFA pin to low and waiting atleast the total trigger time will set all registers by the DSP. For more information please read the SPC Interface section of the manual. The default setup ist: unittime =3.0µs, total trigger time = 90 * 3.0µs = 270 µs t_mlow the time for the first sensor to trigger = 12 * 3.0µs = 36 µs so we have to set the IFA pin 36µs to low, than back to high and wait (90-12)*3.0µs = 224µs SPDX-License-Identifier: MIT
