Notes
1. Power-down state. After power-on the chip is in power-down state as long as the serial clock is not activated. During
power-down all static currents are switched off except the power-on reset block.
2. Output SDOUT is open-circuit; inputs at V DD or V SS ; bus inactive.
3. Drive mode: static, duplex and triplex.
4. LCD outputs are open-circuit, C L = 50 pF typical, inputs at V DD or V SS ; bus inactive.
5. Resets all logic when V DD < V POR .
6. Resistance of output terminal (S1 to S32 and BP1, BP2 and BP3) with a load current of 20 μ A; outputs measured
one at a time.
7. LCD outputs open-circuits.
