on request
Set by the input signal
POR_START_ON_REQ_N.

6 Enable Self
Addressing
Set by the input signal
POR_ADDR_SELF_N
When set input ports are
permitted to address
themselves.
If this bit is not set and a
packet is to be routed
through the same port then
an address error is reported
and the packet is discarded.
When this bit is not set and
a group adaptive routing
packet is received (a packet
which can be routed
through two or more ports,
dependent on the group
adaptive routing table
contents) which can be
routed through the port it
arrived on then the packet
is routed through one of the
other ports and not the port
on which the packet arrived
on. An address error is not
reported.
