Enums

DCOFFG_A

DCO fault flag. If this bit is set, the OFIFG flag is also set. The DCOFFG bit is set if DCO = {0} or DCO = {511}. DCOFFG can be cleared by software. If the DCO fault condition still remains, DCOFFG is set. As long as DCOFFG is set, FLLUNLOCK shows the DCOERROR condition.

ENSTFCNT1_A

Enable start counter for XT1.

FLLULIFG_A

FLL unlock interrupt flag. This flag is set when FLLUNLOCK bits equal 10b (DCO too fast). If FLLULPUC is also set, a PUC is triggered when FLLUIFG is set.

FLLUNLOCKHIS_A

Unlock history bits. These bits indicate the FLL unlock condition history. As soon as any unlock condition happens, the respective bits are set and remain set until cleared by software by writing 0 to it or by a POR.

FLLUNLOCK_A

Unlock. These bits indicate the current FLL unlock condition. These bits are both set as long as the DCOFFG flag is set.

FLLWARNEN_A

Warning enable. If this bit is set, an interrupt is generated based on the FLLUNLOCKHIS bits. If FLLUNLOCKHIS is not equal to 00, an OFIFG is generated.

REFOREADY_A

REFO ready flag. This bit reflects the REFO readiness whent REFO is good for operation (such as FLL reference)

XT1OFFG_A

T1 oscillator fault flag. If this bit is set, the OFIFG flag is also set. XT1OFFG is set if a XT1 fault condition exists. XT1OFFG can be cleared by software. If the XT1 fault condition still remains, XT1OFFG is set.

Type Definitions

DCOFFG_R

Field DCOFFG reader - DCO fault flag. If this bit is set, the OFIFG flag is also set. The DCOFFG bit is set if DCO = {0} or DCO = {511}. DCOFFG can be cleared by software. If the DCO fault condition still remains, DCOFFG is set. As long as DCOFFG is set, FLLUNLOCK shows the DCOERROR condition.

DCOFFG_W

Field DCOFFG writer - DCO fault flag. If this bit is set, the OFIFG flag is also set. The DCOFFG bit is set if DCO = {0} or DCO = {511}. DCOFFG can be cleared by software. If the DCO fault condition still remains, DCOFFG is set. As long as DCOFFG is set, FLLUNLOCK shows the DCOERROR condition.

ENSTFCNT1_R

Field ENSTFCNT1 reader - Enable start counter for XT1.

ENSTFCNT1_W

Field ENSTFCNT1 writer - Enable start counter for XT1.

FLLULIFG_R

Field FLLULIFG reader - FLL unlock interrupt flag. This flag is set when FLLUNLOCK bits equal 10b (DCO too fast). If FLLULPUC is also set, a PUC is triggered when FLLUIFG is set.

FLLULIFG_W

Field FLLULIFG writer - FLL unlock interrupt flag. This flag is set when FLLUNLOCK bits equal 10b (DCO too fast). If FLLULPUC is also set, a PUC is triggered when FLLUIFG is set.

FLLULPUC_R

Field FLLULPUC reader - FLL unlock PUC enable. If the FLLULPUC bit is set, a reset (PUC) is triggered if FLLULIFG is set. FLLULIFG indicates when FLLUNLOCK bits equal 10 (too fast). FLLULPUC is automatically cleared upon servicing the event. If FLLULPUC is cleared (0), no PUC can be triggered by FLLULIFG.

FLLULPUC_W

Field FLLULPUC writer - FLL unlock PUC enable. If the FLLULPUC bit is set, a reset (PUC) is triggered if FLLULIFG is set. FLLULIFG indicates when FLLUNLOCK bits equal 10 (too fast). FLLULPUC is automatically cleared upon servicing the event. If FLLULPUC is cleared (0), no PUC can be triggered by FLLULIFG.

FLLUNLOCKHIS_R

Field FLLUNLOCKHIS reader - Unlock history bits. These bits indicate the FLL unlock condition history. As soon as any unlock condition happens, the respective bits are set and remain set until cleared by software by writing 0 to it or by a POR.

FLLUNLOCKHIS_W

Field FLLUNLOCKHIS writer - Unlock history bits. These bits indicate the FLL unlock condition history. As soon as any unlock condition happens, the respective bits are set and remain set until cleared by software by writing 0 to it or by a POR.

FLLUNLOCK_R

Field FLLUNLOCK reader - Unlock. These bits indicate the current FLL unlock condition. These bits are both set as long as the DCOFFG flag is set.

FLLUNLOCK_W

Field FLLUNLOCK writer - Unlock. These bits indicate the current FLL unlock condition. These bits are both set as long as the DCOFFG flag is set.

FLLWARNEN_R

Field FLLWARNEN reader - Warning enable. If this bit is set, an interrupt is generated based on the FLLUNLOCKHIS bits. If FLLUNLOCKHIS is not equal to 00, an OFIFG is generated.

FLLWARNEN_W

Field FLLWARNEN writer - Warning enable. If this bit is set, an interrupt is generated based on the FLLUNLOCKHIS bits. If FLLUNLOCKHIS is not equal to 00, an OFIFG is generated.

REFOREADY_R

Field REFOREADY reader - REFO ready flag. This bit reflects the REFO readiness whent REFO is good for operation (such as FLL reference)

XT1OFFG_R

Field XT1OFFG reader - T1 oscillator fault flag. If this bit is set, the OFIFG flag is also set. XT1OFFG is set if a XT1 fault condition exists. XT1OFFG can be cleared by software. If the XT1 fault condition still remains, XT1OFFG is set.

XT1OFFG_W

Field XT1OFFG writer - T1 oscillator fault flag. If this bit is set, the OFIFG flag is also set. XT1OFFG is set if a XT1 fault condition exists. XT1OFFG can be cleared by software. If the XT1 fault condition still remains, XT1OFFG is set.
