Note :
1. Power Supply ON Delay (PSON :High → Low). Power Supply is Active when PSON is Low.
2. Power Supply OFF Delay (PSON :Low → High). Power Supply is Off when PSON is High.
3. Ton = (Cpin8 * Von) / lon = (Cpin8 * VthH) / lon
4. Toff = (Cpin8 * Voff) / loff = [Cpin8 * (V8max - VthL)] / (VRd / Rd)
