I2C Remote Write
4 Auto
RW
Acknowledge
Automatically Acknowledge I2C Remote Write.
The mode works when the system is LOCKed.
1: Enable: When enabled, I2C writes to the
Deserializer (or any remote I2C Slave, if I2C PASS
0
ALL is enabled) are immediately acknowledged
without waiting for the Deserializer to acknowledge the
write. The accesses are then remapped to address
specified in 0x06.
0: Disable.
1: Enable Forward Control Channel pass-through of all
I2C accesses to I2C IDs that do not match the
3
I2C Pass-
Through All
RW
Serializer I2C ID. The I2C accesses are then
0
remapped to address specified in register 0x06.
0: Enable Forward Control Channel pass-through only
of I2C accesses to I2C IDs matching either the
remote Deserializer ID or the remote I2C IDs.
2
I2C Pass-
Through
I2C Pass-Through Mode.
RW
1
1: Pass-Through Enabled. DES Alias 0x07 and Slave
Alias 0x09.
0: Pass-Through Disabled.
