WD: Watchdog
WD Disabled: Watchdog disabled (WDCONF terminal connected to GND)
WD Trigger: Watchdog is triggered by SPI command
WD Failed: No watchdog trigger or trigger occurs in closed window
Stop Command: Stop command sent via SPI
Sleep Command: Sleep command sent via SPI
Wake-Up: L1 or L2 state change or LIN bus wake-up or SS rising edge

Notes:
WD - means Watchdog
WD disabled - means Watchdog disabled (WDCONF terminal connected to GND)
WD trigger – means Watchdog is triggered by SPI command
WD failed – means no Watchdog trigger or trigger occurs in closed window
STOP Command - means STOP command sent via SPI
SLEEP Command - means SLEEP command send via SPI
Wake-Up - means L1 or L2 state change or LIN bus wake up or SS rising edge
