0 = switch open (default)
1 = switch closed
d3 Bus 1 Logic State
R
Indicates logic state of downstream
bus 1; only valid when disconnected
from upstream bus
0 = SDA1, SCL1 or both are below 1V
1 = SDA1 and SCL1 are both above
1V
d2 Bus 2 Logic State
R
Indicates logic state of downstream
bus 2; only valid when disconnected
from upstream bus
0 = SDA2, SCL2 or both are below 1V
1 = SDA2 and SCL2 are both above
1V
d1 Bus 3 Logic State
R
Indicates logic state of downstream
bus 3; only valid when disconnected
from upstream bus
0 = SDA3, SCL3 or both are below 1V
1 = SDA3 and SCL3 are both above
1V
d0 Bus 4 Logic State
R
Indicates logic state of downstream
bus 4; only valid when disconnected
from upstream bus
0 = SDA4, SCL4 or both are below 1V
1 = SDA4 and SCL4 are both above
1V
* For Type, “R/W” = Read Write, “R” = Read Only
These bits give the logic state of disconnected downstream buses to
the master, so that the master can choose not to connect to a low
downstream bus. A given bit is a “don’t care” if its associated
downstream bus is already connected to the upstream bus.
