The Busy Flag (BF) indicates the busy state (bit BF = 1) until initialization ends. The busy state lasts 2 ms. The chip may also be

initialized by software (see Table 43 and Table 44).

8.3 Power-down mode

The chip can be put into power-down mode by applying a HIGH-level to pin PD. In

power-down mode all static currents are switched off (no internal oscillator, no bias level

generation and all LCD outputs are internally connected to VSS).

During power-down, information in the RAM and the chip state are preserved. Instruction

execution during power-down is possible when pin OSC is externally clocked.
