DISPLAY
Writes ‘H’.
Writes ‘S’.
Sets DDRAM address 0 in Address Counter. (also returns
shifted display to original position. DDRAM contents
unchanged). This instruction does not update the Data Register
DDRAM content will be read from following instructions.
The R/W has to be set to 1 while still in I
During the acknowledge cycle the content of the DR is loaded
into the internal I
instruction neither a ‘Set address’ nor a ‘Read data’ has been
performed. Therefore the content of the DR was unknown.

acknowledge cycle is shifted out over SDA. MSB is DB7. During
master acknowledge content of DDRAM address 01 is loaded
into the I
SCL; content loaded into interface during previous
