Figure 3. LIN Bus Signal Format
Figure 4. LIN Write and Read Data Frame
The MAX9132/MAX9134/MAX9135 are read using the
devices’ internally stored command bytes as an
address pointer, the same way the stored command
byte is used as an address pointer for a write. The
pointer does not autoincrement after each data byte is
read. Initiate a read by writing the command byte to the
proper slave address (Figure 2), then send the device’s
slave address with the R/W bit set to 1. The slave now
responds with the contents of the requested register
(Figure 2).

ADDRESS
The LIN interface is a low-speed, low-cost interface used
in slow control signal traffic in automotive applications.
This device is the slave node in the LIN bus cluster and
is designed based on the LIN Rev. 1.3 specification. The
LIN master sends data to the MAX9132/MAX9134/
MAX9135 LSB first, up to a maximum data rate of
20kbps. The LIN slave node waits for the synchronization
pulse, then synchronizes itself to the pulse. The node
must then read the identifier and send/receive data bytes
to the master, setting the error flag register when neces-
sary. The LIN interface uses the same routing function of
the switch control registers (0x01, 0x02) as the I
