Notes
1.
2.
If more than one byte DATA is transmitted then the auto-increment of the subaddress is performed.
During slave transmitter mode the SCL-LOW period may be extended by pulling SCL to LOW (in accordance with
the I
2
C-bus specification).
The I
2
C-bus subaddress 00 has to be initialized with 0 before being read.
