How to check whether the SPC560B54L5 EVB IS IN STANDBY mode or not?

[rpoon]

Hello,

I am trying to make SPC560B54L5 EVB in low power mode that is STANDBY mode.

The measured current in normal RUN0 mode is 143 mA whereas while keeping in STANDBY mode, it is around 92 mA. But as per the AN3316 Application note the max current consumption is 314uA. So am I entering into STANDBY mode correctly?

Because I could see that USB is getting disconnected during waiting for the S_MTRANS to SET.

 while (ME.IS.R == 0U){

  ;

 }

How can I make sure rather SPC560B54L5 EVB is in standby mode or not?

BEST REGARDS

Hello Rewatee ,

Maybe you have some measurement issues

I am not an expert to measure a MCU in low power mode

There is a nice example in the application wizard

SPC560Dxx_RLA WKPU API Test Application for Discovery

The core should display Core Inactive on a debug session

Best Regards
