Notes
:
Connection on Test pin:
•
On Flash device, either connect to VSS via a 10kOhm resistor (as close as possible to VSS pad) or foresee a jumper
for programming (VSS or VPP connection)
Connection on pin i.c. (i.c stands for internally connected).
•
This pin is used in EM test modes. No external connection must be made on this pin.
