Power-on reset; first connection of BAT42 or BAT42 below
power-on voltage threshold or RSTN was forced LOW
externally
cyclic wake-up out of Sleep mode
low V1 supply; V1 has dropped below the reset threshold
V1 current above threshold within Standby mode of the
UJA1061 while watchdog OFF behaviour was selected and
the RESET option is selected within the System
Configuration register
V3 voltage is down due to short-circuit occurring during
Sleep mode
reserved
UJA1061 ready to enter Flash Programming mode
wake-up event via CAN while reset behaviour selected or
during Sleep mode
wake-up event via LIN while reset behaviour selected or
during Sleep mode
wake-up event via WAKE while reset behaviour selected or
during Sleep mode
wake-up event out of Fail-safe mode
watchdog overflow (Normal operating mode)/time-out
(Standby mode/Flash mode); trigger too late
watchdog not initialized in time; 256 ms exceeded
watchdog triggered too early; window missed
illegal Mode Register Code
interrupt not served in time (within 256 ms)
reserved for future use; in order to stay compatible with
future silicon versions using this bit, software should ignore
