Hi All,

I would like to know what should be the GPIO configuration in DeepSleep mode for the Cypress TV II CM0 + CM7 CYT4BB5CEBES 4M controller. 

Any preconditions has to be set before entering into deepsleep mode.

I am currently facing below issue

Current consumption 1.5 mA for 3 seconds then jump back to 18.5 mA

What could be the reason and possible fix?

 

Thanks.

Hi,

I have CAN transceiver as wake up source 

It is observed that there is LOW to HIGH and back LOW transition on the STB pin (P19.2) when we execute DeepSleep Mode. This is not observed for Sleep Mode or Hibernet only in DeepSleep mode this behavior is observed.

What could be the reason for this or what should be idle case.

Regards,

Basavaraj
