i.MX502 & MC34709 Power-down sequence

Hello,

 

I'd like to use MC34709 PMIC along with i.MX502.

i.MX502 requires the power-off sequence in the reverse of the power-up.

 

In MC34709 datasheet, there is a power-up sequence for processors.

However there is no descriptions about the power-down sequence.

 

- What is the power-down sequence of MC34079?

- What will happen in i.MX502 if it's not power-down in the reverse of the power-up as instructed in the datasheet?

 

BTW i.MX503 can be powered down "Switch all supplies down simultaneously".

 

Best regards,

Nori Shinozaki
