[DA810] undershoot voltage level for input signal

My customer has a question about the allowed undershoot voltage level for incoming signal on DA810. In the datasheet, there is a spec for output signal (Transient Overshoot/Undershoot) and that is 20% DVDD during 20% signal frequency, but no spec for input. I found the same question here, but it is for OMAPL-138.

Can I understand the same is applicable to DA810 except for 1.8V related descriptions ? DA810 is no support for dual voltage and it only support 3.3V IO voltage.

Hi Senthil,

Ok, thank you. In the data sheet, it says only "Transient" at Input voltage ranges in the table of Absolute Maximum Ratings Over Operating Case Temperature Range, but I regard it as "Transient Overshoot/Undershoot".
