Notes: 1. The maximum possible VLCD voltage that can be generated is dependent on voltage, temperature and (display) load.
2. Internal clock
3. When fsclk = 0 there is no interface clock.
4. Power-down mode. During power-down all static currents are switched-off.
5. If external VLCD, the display load current is not transmitted to IDD
6. Tolerance depends on the temperature; (typically zero at Tamb =27°C), maximum tolerance values are measured at the temper-
ature range limit.
7. For TC0 to TC3
