Function
read Interrupt register
read the Interrupt register without writing to the Interrupt
Enable register
read the Interrupt register and write to the Interrupt Enable
register
a watchdog overflow during Standby mode has caused an
interrupt (interrupt-based cyclic wake-up feature)
no interrupt
the temperature warning status (TWS) has changed
no interrupt
the ground shift diagnosis bit (GSD) has changed
no interrupt
wrong number of CLK cycles (more than, or less than 16)
during SPI access
no interrupt; SPI access is ignored if the number of CLK
cycles does not equal 16
falling edge at pin SENSE has forced an interrupt
no interrupt
V1D, V2D or V3D has been cleared
no interrupt
CAN failure status has changed
no interrupt
reserved for SBCs with LIN transceiver
a negative edge at pin WAKE has been detected
no interrupt
A watchdog restart during watchdog OFF has caused an
interrupt
no interrupt
CAN wake-up event has caused an interrupt
no interrupt
reserved for SBCs with LIN transceiver
