ETAS
Hardware Description
The ETK-S6.0 senses the switched ECU power supply. This allows it to detect
when the ECU is off and forward this information to INCA. In addition, it allows
the ETK to enter the power save mode with the calibration system (ES590/ES591/
ES592/ES595) unplugged.
ECU Reset Detection Delay
To adapt the ETK detection scheme to different system architectures the reset
detection delay of the ETK-S6.0 is configurable: either a short delay of 2
μ
s or an
extended delay of 30
μ
s can be selected via configuration feature. The result is
that the ETK detection pattern is applied to the AUDATA lines for a short period
of time after the reset has been de-asserted. This ensures that the pattern is
safely detected by the ECU.
