Description
Host

device. Notice that by default H = 0.
Initiator
The value of this bit is identical to that of
GCCSR[H], which is assigned by power-on reset
configuration signals. Setting M = 0 disables all
outbound transactions and prevents sending any
outbound packets.
Discovered
The value of this bit is identical to that of
GCCSR[H], which is assigned by power-on reset
configuration signals.
Reserved. Write to zero for future compatibility.
