FT313H Test mode vs Normal mode

(1/1)

t0nyl2:
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?

FTDI Community:
Hello,

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

For normal operation leave floating.

Best Regards,
