19.5.8 Supply Controller Status Register
Name:
SUPC_SR
Address:
0x400E1824
Access:
Read-only
Note: 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.
This register is located in the VDDIO domain.
FWUPS: FWUP Wake-up Status
0 (NO): No wake-up due to the assertion of the FWUP pin has occurred since the last read of SUPC_SR.
1 (PRESENT): At least one wake-up due to the assertion of the FWUP pin has occurred since the last read of SUPC_SR.
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.
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.
