are visible when switched on in the Options menu explicitly or when at
least one of the features is set different from the default value.
We recommend that only experienced users change the default settings.
–
Use Fixed Memory
(Yes, No)
The default value is "No".
The default value is the normal usage of the emulation regions as sep-
arate data regions. With this feature the emulation region of the
microcontroller can be used as one single emulation memory block.
This can be useful to have particular memory maps supported.
Please note that there are further restrictions when using the Fixed
Memory Mode, like there is only one Data region allowed and it needs
to have at least a size of 2 emulation regions (128 KByte). The block
can only start on a 128 KByte alignment border. A further restriction is
that Fixed Memory Mode will not operate together with Limited Emu-
lation Ram Toolbox, but in case of Fixed Memory Mode all Calibration
Variables defined in the A2l must be within this single emulation
memory.

Debug Interface Voltage Level
(3.3 V)
It is set to the fixed value of 3.3 V and can not be changed. This is only
provided for future extensibility.
Currently all supported microcontroller have a 3.3 V interface.

ECU Power Supply Supervision Nominal Voltage
(5.0 V:
thresholds Low
High = 3.15 V, High
Low = 3.50 V,
3.3 V:
thresholds Low
High = 2.33 V, High
Low = 2.68 V,
3.3 V:
thresholds Low
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.

ECU Standby RAM Power Supply Supervision Voltage Span
(Data retention CPU 2.0 V:
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.
