Function Documentation

◆ 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 57 of file pwr.c.

References PWR_CR1, and PWR_CR1_DBP.

◆ pwr_disable_boost()

void pwr_disable_boost ( void  )

Disable Boost Mode.

Definition at line 116 of file pwr.c.

References PWR_CR5, and PWR_CR5_R1MODE.

Here is the caller graph for this function:

◆ pwr_disable_power_voltage_detect()

void pwr_disable_power_voltage_detect ( void  )

Disable Power Voltage Detector.

Definition at line 100 of file pwr.c.

References PWR_CR2.

◆ 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 66 of file pwr.c.

References PWR_CR1.

◆ pwr_enable_boost()

void pwr_enable_boost ( void  )

Enable Boost Mode.

Definition at line 108 of file pwr.c.

References PWR_CR5.

◆ pwr_enable_power_voltage_detect()

void pwr_enable_power_voltage_detect ( uint32_t  pvd_level)

Enable Power Voltage Detector.

Parameters
[in]pvd_levelPower Voltage Detector Falling Threshold voltage PVD level selection.

◆ pwr_set_low_power_mode_selection()

void pwr_set_low_power_mode_selection ( uint32_t  lpms)

Select the low power mode used in deep sleep.

Parameters
lpmslow power mode pwr_cr1_lpms

Definition at line 75 of file pwr.c.
