Figure 10. Writing n Bytes of Data to the MAX9879
MAX9879. Figure 10 illustrates the frame format for writ-
ing n bytes of data to the MAX9879.
The slave address with the R/W bit set to 0 indicates
that the master intends to write data to the MAX9879.
The MAX9879 acknowledges receipt of the address
byte during the master-generated 9th SCL pulse.
The second byte transmitted from the master config-
ures the MAX9879’s internal register address pointer.
The pointer tells the MAX9879 where to write the next
byte of data. An acknowledge pulse is sent by the
MAX9879 upon receipt of the address pointer data.
The third byte sent to the MAX9879 contains the data
that is written to the chosen register. An acknowledge
pulse from the MAX9879 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. Figure
10 illustrates how to write to multiple registers with one
frame. The master signals the end of transmission by
issuing a STOP (P) condition.
Register addresses greater than 0x04 are reserved. Do
not write to these addresses.
