C-bus protocol
Figure 24 shows the definition of the bytes. If bit R/W = 1
the master reads from the read register, if bit R/W = 0 the
master writes to the write register. It is not possible to write
and read the same register.
W
RITE PROTOCOL
Figure 25 shows the protocol for writing to one single
register. After the start command (S) the transmitter sends
the address of the slave device, waits for an acknowledge
from the slave, sends the register address, waits for an
acknowledge, sends data, waits for an acknowledge from
the master followed by a stop condition (P).
R
EAD PROTOCOL
Figure 26 shows the protocol for reading from one or more
registers.
After the start command (S) the receiver sends the
address of the slave device, waits for an acknowledge
from the transmitter slave, receives data from the slave
(slave, TZA3015HW, starts sending data after generating
the acknowledge), after receiving the data, the receiver
(master) sends an acknowledge, or if finished a
not-acknowledge followed by a stop condition (P).

(1) The master receiver must signal an end of data to the slave transmitter by not generating an acknowledge on the last byte that has been clocked
out of the slave.
