Control Register Bit Definitions
Register 0 (00h)
Note: Masters write to Register 0 to reset the fault circuitry after a fault
has occurred and been resolved. Because Register 0 is Read-Only, no
other functionality is affected.
* For Type, “R/W” = Read Write, “R” = Read Only
BIT NAME
d7 Downstream
d6 ALERT1 Logic State
d5 ALERT2 Logic State
d4 Reserved
d3 Reserved
d2 Failed Connection

R
Indicates if upstream bus is connected
to any downstream buses
0 = upstream bus disconnected from
all downstream buses
1 = upstream bus connected to one or
more downstream buses
Logic state of ALERT1 pin, noninverting
Logic state of ALERT2 pin, noninverting
Not Used
Not Used
Indicates if an attempt to connect to a
downstream bus failed because the
“Connection Requirement” bit in
Register 2 was low and the
downstream bus was low
0 = Failed connection attempt occurred
1 = No failed attempts at connection
occurred
Latched bit indicating if a timeout has
occurred and has not yet been cleared.
0 = no latched timeout
1 = latched timeout
Indicates real-time status of Stuck Low
Timeout Circuitry
0 = no timeout is occurring
1 = timeout is occurring
Register 1 (01h)
