Function
read System Diagnosis register
read System Diagnosis register without writing to Mode
register
read System Diagnosis register and write to Mode register
reserved for SBCs with CAN transceiver
TXDL is clamped dominant
LIN is shorted to GND (dominant clamped)
LIN is shorted to VBAT (recessive clamped)
no failure
OK
fail; V3 is disabled due to an overload situation
reserved for SBCs with another voltage regulator
OK; V1 always above V
fail; V1 was below V
again with read access
reserved for SBCs with CAN transceiver
Function
select the Interrupt Enable register
read the Interrupt register
read the Interrupt Enable Feedback register
read the register selected by RRS without writing to
Interrupt Enable register
read the register selected by RRS and write to Interrupt
Enable register
a watchdog overflow during Standby causes an interrupt
instead of a reset event (interrupt based cyclic wake-up
feature)
no interrupt forced on watchdog overflow; a reset is forced
instead
exceeding or dropping below the temperature warning limit
causes an interrupt
no interrupt forced
reserved for SBCs with CAN transceiver
wrong number of CLK cycles (more than, or less than 16)
forces an interrupt; from Start-up mode and Restart mode a
reset is performed instead of an interrupt
no interrupt forced; SPI access is ignored if the number of
cycles does not equal 16
UV(VFI)
LIN fail-safe system basis chip
UV(VFI)
since last read access; bit is set
since last read access
