Hi @pchavapr4,

S32K3xx's only support deep sleep through Standby mode. You can refer to chapter 41.5 from the reference manual. It details the Standby entry sequence. You must switch clock configuration to FIRC before entering Standby.

I suggest looking into these demos. They provide example routines for mode transitions and wake-up configurations:

Best regards,
Julián
