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)

I2C-bus start

PHILIPS

slave address for read

SA6 SA5 SA4 SA3 SA2 SA1 SA0 R/WAck

PHILIPS

during the acknowledge cycle the content of the DR is loaded

into the internal I2C-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;

the R/W has to be set to 1 while still in I2C-write mode

011101011

control byte for read

Ack

PHILIPS

DDRAM content will be read from following instructions

011000001

‘read data’: 8

× SCL + master acknowledge; note 2

DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 Ack

PHILIPS

× 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 I2C-bus interface

XXXXXXXX0

‘read data’: 8

× SCL + master acknowledge; note 2

DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 Ack

PHILIPS

× SCL; code of letter ‘H’ is read ﬁrst; during master

acknowledge code of ‘I’ is loaded into the I2C-bus interface
