Notes

1. X = don’t care.

2. Philips strongly recommends that the extended

command set be used.

3. D7 = MSB.

4. Commands only available with the extended

command set, EXT = 1. If EXT = 0 these commands

have no effect.

5. When icon mode is enabled the set initial display line

is 0

≤ L ≤ 78.

6. When icon mode is enabled the set initial row is

≤ C ≤ 78.

7. Commands only used for the basic command set,

EXT = 0. If EXT = 1 these commands have no effect.

Care should be taken when setting VOP in the basic

command set, it must be followed by another

command.

8. The programming of VOP in the basic command set

must be done in the following order:

a) VPR[5:0]

b) VOFF[2:0]

c) Must be followed by another command.

9. One fixed TC is set automatically if the basic

command set is used.

10. Bias system settings which can be received when the

chip is used as replacement of Alth and Pleskho

driving method (NOP).

11. Only for mux rates 1 : 64 and 1 : 80 the number of

simultaneous rows can be manually set to p = 4.
