ID-number
The STE2004S lets you program a driver identification number (ID-Number), so more than
one LCD module with different configuration parameters can be managed on one platform.
There are four programmable device ID-numbers: 00111100, 00111101, 0011110 and
0011111. All have the first 6 bits (001111) in common. The two least significant bits can be
used to connect the SA0 and SA1 inputs to a VSS or VDD1.
The driver ID-number can be read through all communication interfaces. The way to read
the ID-number changes according the interface selected. The readout protocol for each
interface is described in
