MSPM0G3507: Clarification on Exiting STANDBY Mode in Bootloader

Part Number: MSPM0G3507

Tool/software:

Dear Support Team,

According to the MSPM0 Bootloader User’s Guide:

"In the Interface detection phase, if there is no valid connection command received for 10 seconds over any interface, the bootloader enters STANDBY mode.
POR is required to get out of this state and use Bootloader by creating the BSL invocation condition again."

I would like to confirm whether a POR is also required to wake the device from STANDBY mode and start the existing application. Could you please clarify?

Thank you for your support.

Best regards,
DDdoor

    Hi,

    There are several ways to wake up devices from STANDBY mode. In STANDBY mode (STANDBY0 by default), the MCLK tree runs from LFCLK at 32kHz and SYSOSC is disabled. PD0 peripherals running from the bus clock change to 32kHz. PD0 peripherals running from LFCLK continue to run at 32kHz with no change. All the peripherals in PD0 can weak up the device from STANDBY mode. 

    Best regards,
