Is it possible to stop SPI bus and turn MISO, MOSI and SCK pins to INPUTS?

Sleep stops the loop, then the Application Watchdog will break it out and do a system restart, which because I save the run state of the device to eeprom it recovers this and sends the control back to the controller function for sleeping.

Maybe I should stop trying to help debug this cause I'm really not clear on your setup and code. When you go to (STOP) sleep, the Application Watchdog won't run since FreeRTOS is not running. Are you referring to an external hardware watchdog?
