BIDIRECTIONAL CONTROL BUS - I²C COMPATIBLE
SCL
SDA
MODE
7
Input/Output, Clock line for the bidirectional control bus communication
Open Drain SCL requires an external pull-up resistor to V_DDIO.
8
Input/Output, Data line for the bidirectional control bus communication
Open Drain SDA requires an external pull-up resistor to V_DDIO.
I²C Mode select
MODE = L, Master mode (default); Device generates and drives the SCL clock line.
12
Input, LVCMOS
w/ pull down
Device is connected to slave peripheral on the bus. (Serializer initially starts up in
Standby mode and is enabled through remote wakeup by Deserializer)
MODE = H, Slave mode; Device accepts SCL clock input and attached to an I²C
controller master on the bus. Slave mode does not generate the SCL clock, but uses
the clock generated by the Master for the data transfers.

Input, analog
Device ID Address Select
Resistor to Ground and 10 kΩ pull-up to 1.8V rail. See Table 3
