In the file IfxScuRcu.h at /AURIX_code_examples-master/code_examples/SCU_Reset_Detection_1_KIT_TC397_TFT/Libraries/iLLD/TC39B/Tricore/Scu/Std/, there is a list of reset triggers:
typedef enum
{
IfxScuRcu_Trigger_esr0 = 0, /**< \brief ESR0 */
IfxScuRcu_Trigger_esr1 = 1, /**< \brief ESR1 */
IfxScuRcu_Trigger_smu = 3, /**< \brief SMU */
IfxScuRcu_Trigger_sw = 4, /**< \brief SW */
IfxScuRcu_Trigger_stm0 = 5, /**< \brief STM0 Compare Match */
IfxScuRcu_Trigger_stm1 = 6, /**< \brief STM1 Compare Match */
IfxScuRcu_Trigger_stm2 = 7, /**< \brief STM2 Compare Match */
IfxScuRcu_Trigger_stm3 = 8, /**< \brief STM3 Compare Match */
IfxScuRcu_Trigger_stm4 = 9, /**< \brief STM4 Compare Match */
IfxScuRcu_Trigger_stm5 = 10, /**< \brief STM5 Compare Match */
IfxScuRcu_Trigger_portst = 16, /**< \brief PORTST */
IfxScuRcu_Trigger_cb0 = 18, /**< \brief Cerberus System Reset */
IfxScuRcu_Trigger_cb1 = 19, /**< \brief Cerberus Debug Reset */
IfxScuRcu_Trigger_cb3 = 20, /**< \brief Cerberus Application Reset */
IfxScuRcu_Trigger_tp = 21, /**< \brief Tuning protection */
IfxScuRcu_Trigger_tcu = 22, /**< \brief TCU */
IfxScuRcu_Trigger_evrc = 23, /**< \brief EVRC */
IfxScuRcu_Trigger_evr33 = 24, /**< \brief EVR33 */
IfxScuRcu_Trigger_swd = 25, /**< \brief Supply Watchdog */
IfxScuRcu_Trigger_hsms = 26, /**< \brief HSM System Reset */
IfxScuRcu_Trigger_hsma = 27, /**< \brief HSM Application Reset */
IfxScuRcu_Trigger_stbyr = 28, /**< \brief Standby Regulator Watchdog */
IfxScuRcu_Trigger_undefined = 255 /**< \brief Undefined Value */
} IfxScuRcu_Trigger;
Does SW mean SoftWare and TCU Transmission Control Unit (for CAN0)?
