Hi all

Please tell me the pad condition of i.MX7D during power-up/down sequence.

I'm concerned about whether an unexpected signals are input to the module connected to the CPU during the above period.

I know state the pins of associated to the boot from Table 92 of i.MX7D datasheet.

How about the other pins ?

Hello

  We may use column "PD/PU" in tables, named "functional contact assignments"
of the i.MX7 Datasheets, to define pins state just after reset, but many signals have
no anything in this position. They are assumed as three-state.

Have a great day,
Yuri
