CommunicationProtocol
The STE2001 is an I
2
C slave. The access to the device is bi-directional since data write and status read are allowed.
Two are the device addresses availablefor the device. Both have in common the first 6 bits (011110). The least sig-
nificant bit of the slave address is set by connecting the SA0 input to a logic 0 or to a logic 1.
To start the communicationbetween the bus master and the slaveLCD driver, the master mustinitiate a START con-
dition. Followingthis, the mastersends an 8-bit byte, shown in Fig. 18, on the SDA bus line (Most significant bit first).
This consists of the 7-bit Device selectCode, and the 1-bit Read/Write Designator (R/W).
All slaves with the corresponding address acknowledge in parallel, all the others will ignore the I
2
C-bus transfer.
WritingMode.
If the R/W bit is set to logic 0 the STE2001 is set to be a receiver. After the slaves acknowledge one or more
command word follows to define the status of the device.
A command word is composed by two bytes. The first is a control byte which defines the Co and D/C values,
the second is a data byte (fig 18). The Co bit is the command MSB and defines if after this command will follow
one data byte and an other command word or if will follow a stream of data (Co = 1 Command word, Co = 0
Stream of data). The D/C bit defines whether the data byte is a command or RAM data (D/C = 1 RAM Data, D/
C = 0 Command).
If Co =1 and D/C = 0 the incoming data byte is decoded as a command, and if Co =1 and D/C =1, the following
data byte will be stored in the data RAM at the location specified by the data pointer.
E very byte of a command word must be acknowledged by all addressed units.
After the last control byte, if D/C is setto alogic 1the incoming data bytes are stored inside theSTE2001 Display
RAM starting at the address specified by the data pointer. The data pointer is automatically updated after every
byte written and in the end points to the last RAM location written.
Every byte must be acknowledged by all addressed units.
ReadingMode.
If the R/W bit is set to logic 1 the chip will output data immediately after the slave address. If the D/C bit sent
during the last write access, is set to a logic 0, the byte read is the status byte.
