FT313H Test mode vs Normal mode
« on: May 08, 2020, 03:54:33 PM »

To use the TESTMODE (50h) and TESTPMSET1/2 (70h/74h) on the FT313H, must the TESTEN pin be pulled up?

Is it acceptable to have the TESTEN pulled down externally for normal operation or should it be left floating?

As per the FT313H Datasheet TESTEN pin is to Enable test mode. It has an Internal pull-down.

For normal operation leave floating.
