1. VDD1<=VDD2
2. The maximum possible V_LCD voltage that can be generated is dependent on voltage, temperature and (display) load.
3. When f_sclk = 0 there is no interface clock.
4. If external V_LCD, the display load current is not transmitted to I_DD
5. Internal clock
6. Tolerance depends on the temperature; (typically zero at T_amb = 25°C), maximum tolerance values are measured at the
temperature range limit.
7. Power-down mode. During power-down all static currents are switched-off.
8. For TC0 to TC7
9. Data byte writing mode
