Type Aliases

APC_R

Field APC reader - Apply pull-up and pull-down configuration When this bit is set, the I/O pull-up and pull-down configurations defined in the PWR_PUCRx and PWR_PDCRx registers are applied. When this bit is cleared, the PWR_PUCRx and PWR_PDCRx registers are not applied to the I/Os.

APC_W

Field APC writer - Apply pull-up and pull-down configuration When this bit is set, the I/O pull-up and pull-down configurations defined in the PWR_PUCRx and PWR_PDCRx registers are applied. When this bit is cleared, the PWR_PUCRx and PWR_PDCRx registers are not applied to the I/Os.

EIWUL_R

Field EIWUL reader - Enable internal wakeup line

EIWUL_W

Field EIWUL writer - Enable internal wakeup line

EWUP1_R

Field EWUP1 reader - Enable Wakeup pin WKUP1 When this bit is set, the external wakeup pin WKUP1 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP1 bit in the PWR_CR4 register.

EWUP1_W

Field EWUP1 writer - Enable Wakeup pin WKUP1 When this bit is set, the external wakeup pin WKUP1 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP1 bit in the PWR_CR4 register.

EWUP2_R

Field EWUP2 reader - Enable Wakeup pin WKUP2 When this bit is set, the external wakeup pin WKUP2 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP2 bit in the PWR_CR4 register.

EWUP2_W

Field EWUP2 writer - Enable Wakeup pin WKUP2 When this bit is set, the external wakeup pin WKUP2 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP2 bit in the PWR_CR4 register.

EWUP3_R

Field EWUP3 reader - Enable Wakeup pin WKUP3 When this bit is set, the external wakeup pin WKUP3 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP3 bit in the PWR_CR4 register.

EWUP3_W

Field EWUP3 writer - Enable Wakeup pin WKUP3 When this bit is set, the external wakeup pin WKUP3 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP3 bit in the PWR_CR4 register.

EWUP4_R

Field EWUP4 reader - Enable Wakeup pin WKUP4 When this bit is set, the external wakeup pin WKUP4 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP4 bit in the PWR_CR4 register.

EWUP4_W

Field EWUP4 writer - Enable Wakeup pin WKUP4 When this bit is set, the external wakeup pin WKUP4 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs. The active edge is configured via the WP4 bit in the PWR_CR4 register.

EWUP5_R

Field EWUP5 reader - Enable Wakeup pin WKUP5 When this bit is set, the external wakeup pin WKUP5 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs.The active edge is configured via the WP5 bit in the PWR_CR4 register.

EWUP5_W

Field EWUP5 writer - Enable Wakeup pin WKUP5 When this bit is set, the external wakeup pin WKUP5 is enabled and triggers a wakeup from Standby or Shutdown event when a rising or a falling edge occurs.The active edge is configured via the WP5 bit in the PWR_CR4 register.

Register CR3 reader

RRS_R

Field RRS reader - SRAM2 retention in Standby mode

RRS_W

Field RRS writer - SRAM2 retention in Standby mode

UCPD1_DBDIS_R

Field UCPD1_DBDIS reader - USB Type-C and Power Delivery Dead Battery disable. After exiting reset, the USB Type-C dead battery behavior is enabled, which may have a pull-down effect on CC1 and CC2 pins. It is recommended to disable it in all cases, either to stop this pull-down or to hand over control to the UCPD1 (which should therefore be initialized before doing the disable).

UCPD1_DBDIS_W

Field UCPD1_DBDIS writer - USB Type-C and Power Delivery Dead Battery disable. After exiting reset, the USB Type-C dead battery behavior is enabled, which may have a pull-down effect on CC1 and CC2 pins. It is recommended to disable it in all cases, either to stop this pull-down or to hand over control to the UCPD1 (which should therefore be initialized before doing the disable).

UCPD1_STDBY_R

Field UCPD1_STDBY reader - UCPD1_STDBY USB Type-C and Power Delivery standby mode.

UCPD1_STDBY_W

Field UCPD1_STDBY writer - UCPD1_STDBY USB Type-C and Power Delivery standby mode.
