Detailed Description
Function Documentation
◆ pwr_clear_standby_flag()
| void pwr_clear_standby_flag | ( | void | ) |
Clear the Standby Flag.
This is set when the processor returns from a standby mode.
Definition at line 86 of file pwr_common_v1.c.
References PWR_CR, and PWR_CR_CSBF.
◆ pwr_clear_wakeup_flag()
| void pwr_clear_wakeup_flag | ( | void | ) |
Clear the Wakeup Flag.
This is set when the processor receives a wakeup signal.
Definition at line 97 of file pwr_common_v1.c.
References PWR_CR, and PWR_CR_CWUF.
◆ pwr_disable_backup_domain_write_protect()
| void pwr_disable_backup_domain_write_protect | ( | void | ) |
Disable Backup Domain Write Protection.
This allows backup domain registers to be changed. These registers are write protected after a reset.
Definition at line 38 of file pwr_common_v1.c.
References PWR_CR, and PWR_CR_DBP.
◆ pwr_disable_power_voltage_detect()
| void pwr_disable_power_voltage_detect | ( | void | ) |
◆ pwr_disable_wakeup_pin()
| void pwr_disable_wakeup_pin | ( | void | ) |
Release Wakeup Pin.
The wakeup pin is used for general purpose I/O.
Definition at line 159 of file pwr_common_v1.c.
References PWR_CSR.
◆ pwr_enable_backup_domain_write_protect()
| void pwr_enable_backup_domain_write_protect | ( | void | ) |
Re-enable Backup Domain Write Protection.
This protects backup domain registers from inadvertent change.
Definition at line 49 of file pwr_common_v1.c.
References PWR_CR.
◆ pwr_enable_power_voltage_detect()
| void pwr_enable_power_voltage_detect | ( | uint32_t | pvd_level | ) |
Enable Power Voltage Detector.
This provides voltage level threshold detection. The result of detection is provided in the power voltage detector output flag (see pwr_voltage_high) or by setting the EXTI16 interrupt (see datasheet for configuration details).
- Parameters
-
[in] pvd_level uint32_t. Taken from PVD level selection.

References PWR_CR, and PWR_CR_PVDE.
◆ pwr_enable_wakeup_pin()
| void pwr_enable_wakeup_pin | ( | void | ) |
Enable Wakeup Pin.
The wakeup pin is used for waking the processor from standby mode.
Definition at line 148 of file pwr_common_v1.c.
References PWR_CSR, and PWR_CSR_EWUP.
◆ pwr_get_standby_flag()
| bool pwr_get_standby_flag | ( | void | ) |
Get Standby Flag.
The standby flag is set when the processor returns from a standby state. It is cleared by software (see pwr_clear_standby_flag).
- Returns
- boolean: TRUE if the processor was in standby state.
Definition at line 188 of file pwr_common_v1.c.
References PWR_CSR, and PWR_CSR_SBF.
◆ pwr_get_wakeup_flag()
| bool pwr_get_wakeup_flag | ( | void | ) |
Get Wakeup Flag.
The wakeup flag is set when a wakeup event has been received. It is cleared by software (see pwr_clear_wakeup_flag).
- Returns
- boolean: TRUE if a wakeup event was received.
Definition at line 202 of file pwr_common_v1.c.
References PWR_CSR, and PWR_CSR_WUF.
◆ pwr_set_standby_mode()
| void pwr_set_standby_mode | ( | void | ) |
Set Standby Mode in Deep Sleep.
Definition at line 107 of file pwr_common_v1.c.
References PWR_CR, and PWR_CR_PDDS.
◆ pwr_set_stop_mode()
| void pwr_set_stop_mode | ( | void | ) |
◆ pwr_set_vos_scale()
| void pwr_set_vos_scale | ( | enum pwr_vos_scale | scale | ) |

◆ pwr_voltage_high()
| bool pwr_voltage_high | ( | void | ) |
Get Voltage Detector Output.
The voltage detector threshold must be set when the power voltage detector is enabled, see pwr_enable_power_voltage_detect.
- Returns
- boolean: TRUE if the power voltage is above the preset voltage threshold.
