STE2004
6 ID-NUMBER
The STE2004 allows to program a Driver Identification Number (ID-Number). This make possible to easily
manage on one platform more than one LCD module with different configuration parameters.
Four are the device ID-Numbers programmable: 00111100, 00111101, 0011110 & 0011111. All have in
common the first 6 bits (001111). The two least significant bit could be set connecting 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-out the ID-Num-
ber changes according the interface selected. The readout protocol for each interface is described in the
Bus interfaces paragraph.
