FLAGS AND DEVICE STATUS
INT
INT request
Description
Report that INT source is an INT request from a SPI command.
Set / Reset condition
Set: INT occurred. Reset: flag read (SPI)
RST high
Description
Report that RST pin is shorted to high voltage.
Set / Reset condition
Set: RST failure detection. Reset: flag read.
DBG resistor
Description
Report that the resistor at DBG pin is different from expected (different from SPI register content).
Set / Reset condition
Set: failure detected. Reset: correct resistor and flag read (SPI).
VDD TEMP PRE-
WARNING
Description
Report that the VDD has reached overtemperature pre-warning threshold.
Set / Reset condition
Set: VDD thermal sensor above threshold. Reset: VDD thermal sensor below threshold and flag read
(SPI)
VDD UV
Description
Reports that VDD pin is lower than the VDDUV threshold.
Set / Reset condition
Set: VDD below threshold for t >100
s typically. Reset: VDD above threshold and flag read (SPI)
VDD
overVOLTAGE
Description
Reports that VDD pin is higher than the typically VDD + 0.6 V threshold. I/O-1 can be turned OFF if
this function is selected in INIT register.
Set / Reset condition
Set: VDD above threshold for t >100
s typically. Reset: VDD below threshold and flag read (SPI)
VAUX_overVOL
TAGE
Description
Reports that VAUX pin is higher than the typically VAUX + 0.6 V threshold. I/O-1 can be turned OFF if
this function is selected in INIT register.
Set / Reset condition
Set: VAUX above threshold for t >100 s typically. Reset: VAUX below threshold and flag read (SPI)
VDD LOW
>100 ms
Description
Reports that VDD pin is lower than the VDDUV threshold for a time longer than 100 ms
Set / Reset condition
Set: VDD below threshold for t >100 ms typically. Reset: VDD above threshold and flag read (SPI)
VDD LOW
Description
Report that VDD is below VDD undervoltage threshold.
Set / Reset condition
Set: VDD below threshold. Reset: fag read (SPI)
VDD (5.0 V or
3.3 V)
Description
0: mean 3.3 V VDD version
1: mean 5.0 V VDD version

Description
Report that the more than 8 consecutive reset pulses occurred, due to missing or wrong watchdog
refresh.
Set / Reset condition
Set: after detection of multiple reset pulses. Reset: flag read (SPI)
watchdog
refresh failure
Description
Report that a wrong or missing watchdog failure occurred.
Set / Reset condition
Set: failure detected. reset: flag read (SPI)
