Hi, I saw that in short time a lot of professionals looks at this post, so I presume that it could be of interest for many people to have an answer.

So, pls, if a Nxp professional or the software architect that wrote the code, could give an answer, I would be very greatfull!!

Gianluca.

Hi Gianluca Peterle,

All you need can be found in UM10858. Please refer to the following for details.

7.3.2.1 Entering Standby Mode
To enter standby mode, the firmware needs to operate in an infinite while loop of:
1. Programming the standby bit in the PCR_CTRL_REG.
2. Checking if there is any standby prevention reason.

3. If any reason found, then cater to the reason preventing entry of standby
Go back to step 1.
This loop will be automatically broken when PN7462AU enters standby and comes out. As this will reset PN7462AU and restart the boot.

Hope that helps,

Have a great day,
Kan

hello @Kan_Li ,

Can you please provide a sample example to switch from active mode to standby and hard power-down mode?
