Figure 11 – I C Waveforms Showing Read Message Format
The protocol of the I²C bus is as follows:
Clock is always from the MASTER
Device Address is different for a WRITE (0x68) than for a
READ (0x69)
The SLAVE or MASTER when not outputting data leaves the
data line high
The SLAVE acknowledges each BYTE written to it
The MASTER has the option of acknowledging the last
READ BYTE of data
Each message begins with a START and ends with a STOP
Each message has DEVICE ADDRESS, REGISTER ADDRESS,
and then DATA
MASTER can write incrementing registers by just adding
DATA BYTES to message
When writing multi Data BYTES, add data to end of single
DEVICE, REGISTER ADDRESS
