Hi NXP community,

I am working on SPI protocol to R/W SD card.

I am using bare metal code from S32K1xx cookbook, I have found this doze mode bit in CR register.

Can anyone please tell me what is this bit will do exactly if I am enabling it.

I have referred RM, Still I can not clear myself.

Hi @vignesh3

Peripheral Doze mode is a low-power feature that allows certain peripherals to remain active while the CPU is in a low-power state.

This topic has been discussed in other threads as well. I recommend reviewing those discussions, as they may provide additional insights that could be helpful.

How is the Doze mode working in S32K series

What is the role of DOZE mode of many modules
