- * Name: stm32_pmstop
- *
- * Description:
- * Enter STOP mode.
- *
- * Input Parameters:
- * lpds - true: To further reduce power consumption in Stop mode, put the
- * internal voltage regulator in low-power mode using the LPDS bit
- * of the Power control register (PWR_CR).
- *
- * Returned Value:
- * Zero means that the STOP was successfully entered and the system has
- * been re-awakened. The internal volatage regulator is back to its
- * original state. Otherwise, STOP mode did not occur and a negated
- * errno value is returned to indicate the cause of the failure.

- * Input Parameters:
- * None

- * Returned Value.
- * On success, this function will not return (STANDBY mode can only be
- * terminated with a reset event). Otherwise, STANDBY mode did not occur

- * Name: stm32_pmsleep
- *
- * Description:

- *
- * Input Parameters:
- * sleeponexit - true: SLEEPONEXIT bit is set when the WFI instruction is
- * executed, the MCU enters Sleep mode as soon as it
- * exits the lowest priority ISR.
- * - false: SLEEPONEXIT bit is cleared, the MCU enters Sleep mode
- * as soon as WFI or WFE instruction is executed.
- * Returned Value:
- * Zero means that the STOP was successfully entered and the system has
- * been re-awakened. The internal volatage regulator is back to its
- * original state. Otherwise, STOP mode did not occur and a negated
- * errno value is returned to indicate the cause of the failure.
