Two-Wire Serial Interface Configuration in Stereoscopic Mode
In stereoscopic mode, the two sensors are required to run in lockstep. This implies that
control logic in each sensor is in exactly the same state as its pair on every clock. To
ensure this, all inputs that affect control logic must be identical and arrive at the same
time at each sensor.
These inputs include:
• system clock
• system reset
• two-wire serial interface clk - SCL
• two-wire serial interface data - SDA
The setup in Figure 8 shows how the two sensors can maintain lockstep when their
configuration registers are written through the two-wire serial interface. A WRITE to
configuration registers would either be broadcast (simultaneous WRITES to both
sensors) or individual (WRITE to just one sensor at a time). READs from configuration
registers would be individual (READs from just one sensor at a time).
One of the two serial interface slave address bits of the sensor is hardwired. The other is
controlled by the host. This allows the host to perform either a broadcast or a one-to-
one access.
Broadcast WRITES are performed by setting the same S_CTRL_ADR input bit for both
slave and master sensor. Individual WRITES are performed by setting opposite
S_CTRL_ADR input bit for both slave and master sensor. Similarly, individual READs are
performed by setting opposite S_CTRL_ADR input bit for both slave and master sensor.

All system clock lengths (L) must be equal.
SCL and SDA lengths to each sensor (from the host) must also be equal.
