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
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.
The serializer supports I
eral on the remote side of the communication link using
SCL clock stretching. While multiple masters can reside
on either side of the communication link, arbitration is
not provided. The connected masters need to support
SCL clock stretching and provide contention detection.

addresses (address to translate to) are stored in registers
0x0A and 0x0C.
The serializer supports broadcast commands to control
multiple peripheral devices. Select an unused device
address to use as a broadcast device address. Program
the remote-side GMSL device to translate the broadcast
device address (source address stored in registers 0x09,
0x0B) to the peripheral device address (destination
address stored in registers 0x0A, 0x0C). Any commands
sent to the broadcast address are sent to all designated
peripherals, while commands sent to a peripheral’s unique
device address are sent to that particular device only.
