clock amplitude inquiry on 32kHz crystal

I'm using Kinetis K81 family mcu.

In the specification for the 32kHz clock for EXTAL32 , it was specified that the typical peak-to-peak amplitude of oscillation is 0.6V and no tolerance was given.

My actual measurement on the amplitude is 0.55V.   I would like to ask if this will normally work or what voltage range should be I'm looking at.

Hi,

From the data sheet, there has a specification on the 32kHz OSC:
