Parameter
Short Description
Programmability
Yes (parity can be disabled).
In-System Testability
Yes.
For more details, see Chapter 2.4.4.4.
The SPI Error Detection Mechanism can be tested by inserting on purpose a dedicated error and by verifying that
the device’s reaction is conform to specification.
3.4.5 Active Short Circuit Support
The Active Short Circuit Support Function is summarized in Table 3-12:

Parameter
Short Description
Function
Notification in case V_CC2 is below the UVLO2 threshold or internal digital supply
not valid.
Periodicity
Continuous.
Action in case of failure event Signal NUV2 activated.
Programmability
No.
In-System Testability
Yes.
This feature is aimed at being used in combination with a booster device supporting a direct turn-on input (pin ASC,
see Figure 3-8). Any time the voltage V_CC2 goes below threshold V_UVLO2L,or the internal digital voltage supply is
not valid, the open drain pin NUV2 drives a low level for the duration of the event.

The NUV2 pin functionality can be tested on system level by creating the conditions of its activation and verifying
that the reaction of the device corresponds to the expected behavior.
