TCRAM Contents in PSS Mode in Traveo S6J3XXX Series MCUs – KBA228169

Version: **

 

Question:

If the MCU wakes up from PSS (Power Saving State), the RAM value is undefined. Why?

 

Answer:

In PSS, TCRAM power is not supplied. Therefore, the TCRAM value is undefined.

If you have data that you want to keep in PSS, save it in BackupRAM. BackupRAM has an area where power is supplied even in PSS.

For details, see the “Low Power Consumption” section in the following documents.
