Difference for stop modes

[prudhvichitturi]

Hello ,

I have used the below to go into stop mode:

  HAL_PWR_EnterSTOPMode( PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI ); /* CPU will be halted here until a wakeup event occurs */

in  the above function, what is the difference

PWR_SLEEPENTRY_WFI  & PWR_STOPENTRY_WFI as parameter?

Hello @prudhvichitturi 

PWR_STOPENTRY_WFI is used as a parameter of the HAL_PWR_EnterSTOPMode() function to enter STOP mode with WFI instruction. But the PWR_SLEEPENTRY_WFI should be used as a parameter for the HAL_PWR_EnterSLEEPMode() function to enter SLEEP mode with WFI instruction. More details are provided on the pages 384 and 385 of the UM1749 Rev7.

Best Regards.

PWR_SLEEPENTRY_WFI  was used HAL_PWR_EnterSTOPMode() , what are the effects when used?

[STTwo-32 · Accepted solution]

Since the two macros have the same values: 

using PWR_SLEEPENTRY_WFI with HAL_PWR_EnterSTOPMode() will not be a problem (the function will work as expected with PWR_STOPENTRY_WFI).
