Figure 18. Writing 1 Byte of Data to the IC
Figure 19. Writing n-Bytes of Data to the IC
Write Data Format
A write to the IC includes transmission of a START con-
dition, the slave address with the R/W bit set to 0, one
byte of data to configure the internal register address
pointer, one or more bytes of data, and a STOP condi-
tion. Figure 18 illustrates the proper frame format for
writing one byte of data to the IC. Figure 19 illustrates
the frame format for writing n-bytes of data to the IC.
The slave address with the R/W bit set to 0 indicates
that the master intends to write data to the IC. The IC
acknowledges receipt of the address byte during the
master-generated ninth SCL pulse.
The second byte transmitted from the master configures
the IC’s internal register address pointer. The pointer tells
the IC where to write the next byte of data. An acknowl-
edge pulse is sent by the IC upon receipt of the address
pointer data.
The third byte sent to the IC contains the data that are
written to the chosen register. An acknowledge pulse
from the IC signals receipt of the data byte. The address
pointer autoincrements to the next register address after
each received data byte. This autoincrement feature
allows a master to write to sequential registers within one
continuous frame. The master signals the end of trans-
mission by issuing a STOP condition. Register addresses
greater than 0x12 are reserved. Do not write to these
addresses.
