Configuration 1
When enabled, I

C writes to the Deserializer (or
any remote I
2
C Slave, if I
2
C PASS ALL is
enabled) are immediately acknowledged
without waiting for the Deserializer to
2 AUTO ACK RW 0
acknowledge the write. The accesses are then
remapped to address specified in 0x06. This
allows I2C bus without LOCK.
