Hi Champs,


I noticed in AM24/AM64 there is a DRV_STR bit in PADMMR_PADCONFIGxx Register that can control GPIO drive strength. Now customer want to know does AM2634 have this function? I can't find it in TRM and code. Could you please help to check it? Thanks!

Best Regards,

Julia

    Hello Julia,

    AM2634 does not have a drive strength control function for the GPIO. All GPIO are spec'd at IOL/IOH drive strength of 6mA. If a GPIO is configured for I2C Open-Drain the drive strength is then 3mA.
