Maximum value of VIH and VOH

Hello,

i would like to use DA14580 device with external 3.3V logics.
i have been reading Datasheet v1.63 to find VIH and VOH's max value but could not (it is blank).
[ Q ] How those parameters specified? Is it same as VBAT3V value?

# i see absolute max is 3.6V on any pins so i understand it should be less than that.

Thanks && Regards,
Kazuki

VIH and VOH max values are

VIH和VOH VBAT3马克斯值V (though they are depends on load current).
The absolute max is the value which can be allowed to enter a moment. Usually the max value of input is VBAT3V.

Thanks,
