High = 2.55 V, High
Low = 2.90 V)
The default value is "5.0 V".
The level for power voltage level supervision can be set here. To display
the properties of the used voltage comparators the Low
High and
High
Low thresholds are shown as well.
The "ETK Configuration Tool" window "ETK Control Panel" displays
both power supply supervision states.

thresholds Low
High = 2.00 V, High
Low = 2.30 V,
Data retention CPU 2.7 V:
thresholds Low
High = 2.70 V, High
Low = 3.00 V)
The default value is "Data retention of CPU 2.7 V".
The level for the level supervision of the ECU RAM Standby can be set
here. To display the properties of the used voltage comparators the
Low
High and High
Low thresholds are shown as well.
–
AUD Clock Speed
(10 MHz and 20 MHz)
The default value is "20 MHz".
The ETK can operate with two AUD interface clock speeds. Please note
that the performance of the measurement system and thus the num-
ber of variables that can be selected depends on the AUD clock speed.
For best performance we recommend to use the default of 20 MHz.
–
Trigger register polling rate
(12 steps between 10
μ
s and 50 ms)
The default value is "50
μ
s".
This defines the rate with which the ETK polls the trigger register of the
microcontroller used for Handshake during init and signaling trigger
from the ECU.
–
Reset Delay
(2
μ
s and 30
μ
s)
The default value is "2
μ
s".
This specifies if the microcontroller stays in reset longer than the actual
reset signal is present. This information is important for the ETK to
allow a proper handshake after reset allow an detection the ETK by the
ECU.

Subtype ETK-S6.0B
In this setting the ETK-S6.0 uses the JTAG H-UDI interface to interface the micro-
controller.
•
Microcontroller
(SH72531F, SH72531FCC, SH72533FCC)
The default value is "SH72531FCC".
The memory layout of these microcontrollers differs significantly, so the
ETK Configuration Tool needs know which one is used.
