How to use the Schmitt Trigger function when GPIO is switched to I²C mode? Issue Date：2016-08-29

When GPIO is set to I²C mode, Schmitt Trigger is disabled by default. Users have to set GPIO Input Type Control to enable the Schmitt Trigger.

For example, in the NUC240 series, GPA_MFP8 and GPA_MFP9 need to be set to I²C mode.

Then, enable the Schmitt Trigger of GPA_TYPE8 and GPA_TYPE9.
