5.2.4.1
If the supply voltage
information remains intact and uncorrupted. The “undervoltage” (Power Supply Fail, PSF) error bit is flagged and
can be read out via SPI. Once
are restarted and the PSF error bit is reset.
5.2.4.2
If the supply voltage
“overvoltage” (PSF) error bit is set. The error is not latched, i.e. if

5.2.5
The following reset triggers have been implemented in the TLE84106EL:-
V
The SPI Interface shall not function if
initialized. The output stages are switched off to High-Z. The undervoltage reset and SRR is released once
voltage levels are above the undervoltage threshold,
Reset on INH pin:
If the INH pin level is low, the device shall enter reset and the current consumption is reduced to
