28-Bit GMSL Deserializer for Coax or STP Cable

Figure 25. Slave Address
Slave Address
The serializer/deserializer have a 7-bit-long slave address.
The bit following a 7-bit slave address is the R/W bit, which
is low for a write command and high for a read command.
The slave address is 100100X1 for read commands and
100100X0 for write commands. See Figure 25.
Bus Reset
The device resets the bus with the I2C START condition
for reads. When the R/W bit is set to 1, the serializer/
deserializer transmit data to the master, thus the master
is reading from the device.
Format for Writing
A write to the serializer/deserializer comprises the trans-
mission of the slave address with the R/W bit set to zero,
followed by at least one byte of information. The first
byte of information is the register address or command
byte. The register address determines which register of
the device is to be written by the next byte, if received.
If a STOP (P) condition is detected after the register
address is received, the device takes no further action
beyond storing the register address (Figure 26). Any
bytes received after the register address are data bytes.
The first data byte goes into the register selected by the
register address, and subsequent data bytes go into
subsequent registers (Figure 27). If multiple data bytes
are transmitted before a STOP condition, these bytes
are stored in subsequent registers because the register
addresses autoincrement.
Format for Reading
The serializer/deserializer are read using the internally
stored register address as an address pointer, the same
way the stored register address is used as an address
pointer for a write. The pointer autoincrements after each
data byte is read using the same rules as for a write. Thus,
a read is initiated by first configuring the register address
by performing a write (Figure 28). The master can now
read consecutive bytes from the device, with the first data
byte being read from the register address pointed by
the previously written register address. Once the master
sends a NACK, the device stops sending valid data.
