CAMERA MODE OPERATION
In Camera mode, I
controller at the Deserializer side
core in the Deserializer will detect if a transaction is intended
for the Serializer or a slave at the Serializer. Commands are
sent over the bidirectional control channel to initiate the trans-
actions. The Serializer will receive the command and gener-
ate an I
the Serializer will capture the response on the I
return the response on the forward channel link. The Deseri-
alizer parses the response and passes the appropriate re-
sponse to the Deserializer I
To configure the devices for camera mode operation, set the
Serializer MODE pin to Low and the Deserializer MODE pin
to High. Before initiating any I
needs to be programmed with the target slave device ad-
dresses and Serializer device address. SER_DEV_ID Regis-
ter 0x07h sets the Serializer device address and
SLAVE_x_MATCH/SLAVE_x_INDEX
0x08h~0x17h set the remote target slave addresses. In slave
mode the address register is compared with the address byte
sent by the I
registers values, the I
bus to propagate the transaction to the target device other-
wise it returns no acknowledge.
