Control byte:
Co = 1; RS = 0; R/W = 0; Ack = 1
Return home:
DB7 = 0; DB6 = 0; DB5 = 0; DB4 = 0; DB3 = 0; DB2 = 0;
DB1 = 1; DB0 = 0; Ack = 1

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 (DR).
The R/W has to be set to 1 while still in I

C-bus write
mode.

During the acknowledge cycle the content of the DR is
loaded into the internal I
2
C-bus interface to be shifted out.
In the previous instruction neither a ‘Set address’ nor a
‘Read data’ has been performed. Therefore the content of
the DR was unknown.

SCL; content loaded into interface during previous
acknowledge cycle is shifted out over SDA. MSB is DB7.
During master acknowledge content of DDRAM
address 01 is loaded into the I
2
C-bus interface.

×
SCL; code of letter ‘H’ is read first. During master
acknowledge code of ‘I’ is loaded into the I

interface.
No master acknowledge; After the content of the I

C-bus
interface register is shifted out no internal action is
performed. No new data is loaded to the interface register,
Data Register (DR) is not updated, Address Counter (AC)
is not incremented and cursor is not shifted.
