Part Number: AM4378

Hello,

If we set SLEWCTRL=1(Slow) of Pad Control Registers of AM437x,
slew rate becames slow ?

from these posts...

I understand no changes will occur between SLEWCTRL=0 and 1 in AM335x because
AM335x does not support SLEWCTRL=1(Slow).

How about AM437x ? same to AM335x?

Hi,

Yes, the same statement can be found in section 5.13.3 of the AM437x Datasheet Rev. D:

"The timing parameter values specified in this data manual assume the SLEWCTRL bit in each pad control register is configured for fast mode (0b)."

OK, I understand that AM437x doesn't support SLEWCTRL=1(Slow) too.
Thanks,
