I2C Passthrough
Automatically Acknowledge I2C Remote Write
When enabled, I2C writes to the Deserializer (or
any remote I2C Slave, if I2C PASS 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. This
allows I2C bus without LOCK.
