stm32l4, swd, shutdown/standby

Is it possible to wake an stm32l4 from shutdown or standby modes using the swd interface and swd protocol ?    I know it is possible to set control bits that enable debug during shutdown/standby, but I'm asking something different -- to wake the chip if these control bits haven't been set.

The only external ways to wake the stm32l4 that I'm relatively sure of are yanking the reset pin, or where enabled by software, a wakeup pin.

Hello,

You can wake up from Standby/Shutdown using wakeup pin, RTC or Reset.
