OSCSEL: 32 kHz Oscillator Selection Status
0 (RC) = The slow clock, SLCK is generated by the embedded 32 kHz RC oscillator.
1 (CRYST) = The slow clock, SLCK is generated by the 32 kHz crystal oscillator.
LCDS: LCD Status
0 (DISABLED) = LCD controller is disabled.
1 (ENABLED) = LCD controller is enabled.
LPDBCS2: Low-Power Debouncer Tamper Status on WKUP14/TMP2
0 (NO) = No tamper detection or wake-up due to the assertion of the WKUP14/TMP2 pin has occurred since the last read of
SUPC_SR.
1 (PRESENT) = At least one tamper detection and wake-up (if enabled by WKUPEN14) due to the assertion of the
WKUP14/TMP2 pin has occurred since the last read of SUPC_SR. The SUPC interrupt line is asserted while LPDBCS2 is 1.
LPDBCS3: Low-Power Debouncer Tamper Status on WKUP15/TMP3
0 (NO) = No tamper detection or wake-up due to the assertion of the WKUP15/TMP3 pin has occurred since the last read of
SUPC_SR.
1 (PRESENT) = At least one tamper detection and wake-up (if enabled by WKUPEN15) due to the assertion of the
WKUP15/TMP3 pin has occurred since the last read of SUPC_SR. The SUPC interrupt line is asserted while LPDBCS2 is 1.
FWUPIS: FWUP Input Status
0 (LOW) = FWUP input is tied low.
1 (HIGH) = FWUP input is tied high.
LPDBCS0: Low-Power Debouncer Wake-up Status on WKUP0/TMP0
0 (NO) = No tamper detection or wake-up due to the assertion of the WKUP0/TMP0 pin has occurred since the last read of
SUPC_SR.
1 (PRESENT) = At least one tamper detection and wake-up (if enabled by WKUPEN0) due to the assertion of the WKUP0/TMP0
pin has occurred since the last read of SUPC_SR. The SUPC interrupt line is asserted while LPDBCS0 is 1.
LPDBCS1: Low-Power Debouncer Wake-up Status on WKUP10/TMP1
0 (NO) = No tamper detection or wake-up due to the assertion of the WKUP10 pin has occurred since the last read of SUPC_SR.
1 (PRESENT) = At least one tamper detection and wake-up (if enabled by WKUPEN10) due to the assertion of the
WKUP10/TMP1 pin has occurred since the last read of SUPC_SR. The SUPC interrupt line is asserted while LPDBCS1 is 1.
BUPPORS: Backup Area Power-On Reset Status
0 (BUPPOR_DISABLED) = Backup POR is disabled.
1 (BUPPOR_ENABLED) = Backup POR is enabled.
Note:
The value written in BUPPOREN is effective when BUPPORENS is carrying the same value in
”Supply Controller
Status Register”
.
WKUPISx: WKUPx Input Status
0 (DIS) = The corresponding wake-up input is disabled, or was inactive at the time the debouncer triggered a wake-up event.
1 (EN) = The corresponding wake-up input was active at the time the debouncer triggered a wake-up event.
