Write Data Format
A write to the MAX9851/MAX9853 includes transmission
of a START condition, 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
condition. Figure 13 illustrates the proper frame format for
writing one byte of data to the MAX9851/MAX9853.
Figure 14 illustrates the frame format for writing n-bytes of
data to the MAX9851/MAX9853.
The slave address with the R/W bit set to 0 indicates
that the master intends to write data to the MAX9851/
MAX9853. The MAX9851/MAX9853 acknowledge
receipt of the address byte during the master-generat-
ed ninth SCL pulse.
The second byte transmitted from the master configures
the MAX9851/MAX9853’s internal register address point-
er. The pointer tells the MAX9851/MAX9853 where to
write the next byte of data. An acknowledge pulse is sent
by the MAX9851/MAX9853 upon receipt of the address
pointer data.
The third byte sent to the MAX9851/MAX9853 contains
the data that will be written to the chosen register. An
acknowledge pulse from the MAX9851/MAX9853 sig-
nals receipt of the data byte. The address pointer auto
increments to the next register address after each
received data byte. This autoincrement feature allows a
master to write to sequential registers within one contin-
uous frame. Figure 14 illustrates how to write to multiple
registers with one frame. The master signals the end of
transmission by issuing a STOP condition.
Register addresses greater than 0x1B are reserved. Do
not write to these addresses.
