AM62P: Processors forum

Hi team.

Could you answer the following question?

Now, we are currently designing a circuit board using AMP62P and checking the EVB (SK-AM62P-LP) schematics for reference.

Why is only the RESET of Ethernet PHY-IC connected to PORz_OUT pin?

(On the other hand, other devices are connected to RESETSTATz.)

    Hello tsubasa.hatada,

    Thank you for the query.

    Please read the below note in the TRM

    NoteNotePORz_OUT may be used to enable and/or disable output buffers of attached devices that share pins associated with BOOTMODE inputs, such that appropriate boot configuration values are allowed to propagate into the device without contention.

     The EPHY used has pin straps that are latched during reset.

    Regards,
