*)NC pin number : No. 33, 34, 47, 48, 49, 50, 63, 64 NC: No Connection. Leave these pins open.
2)External resister 4.7 kΩ±1% should be connected between IREF and VSS.
3)External resister should be connected between PLA and VSS.
Normally 1.33kΩ is connected for DS3/STS-1 or 1.27kΩ for E3.
4)Pulled up to VDD with internal register. (typical 50k Ω)
