AM3352: GPMC, Bus holder

Oba

Part Number: AM3352

Hello,

Do GPMC_ADx pins of AM335x have bus holder function?
As far as I checked in TRM and the datasheet, I cound't find any description. So I guess it doesn't have.
But I just want to confirm it just in case.

Regards,
Oba

Hello Oba,

GPMC pins are multiplexed/shared LVCMOS pins. They are controlled through Pad config registers and there would be a bit controlling Bus holder (or Bus keeper) along with pull-up/pull-down controls, if bus holder function existed:

Best Regards,
