Note:
• WKUPS: WKUP Wake Up Status
0 (NO) = no wake up due to the assertion of the WKUP pins has occurred since the last read of SUPC_SR.
1 (PRESENT) = at least one wake up due to the assertion of the WKUP pins has occurred since the last read of SUPC_SR.
• SMWS: Supply Monitor Detection Wake Up Status
0 (NO) = no wake up due to a supply monitor detection has occurred since the last read of SUPC_SR.
1 (PRESENT) = at least one wake up due to a supply monitor detection has occurred since the last read of SUPC_SR.
• BODRSTS: Brownout Detector Reset Status
0 (NO) = no core brownout rising edge event has been detected since the last read of the SUPC_SR.
1 (PRESENT) = at least one brownout output rising edge event has been detected since the last read of the SUPC_SR.
When the voltage remains below the defined threshold, there is no rising edge event at the output of the brownout detec-
tion cell. The rising edge event occurs only when there is a voltage transition below the threshold.
• SMRSTS: Supply Monitor Reset Status
0 (NO) = no supply monitor detection has generated a core reset since the last read of the SUPC_SR.
1 (PRESENT) = at least one supply monitor detection has generated a core reset since the last read of the SUPC_SR.
• SMS: Supply Monitor Status
0 (NO) = no supply monitor detection since the last read of SUPC_SR.
1 (PRESENT) = at least one supply monitor detection since the last read of SUPC_SR.
• SMOS: Supply Monitor Output Status
0 (HIGH) = the supply monitor detected VDDIO higher than its threshold at its last measurement.
1 (LOW) = the supply monitor detected VDDIO lower than its threshold at its last measurement.

Because of the asynchronism between the Slow Clock (SCLK) and the System Clock (MCK), the status register flag reset is
taken into account only 2 slow clock cycles after the read of the SUPC_SR.
