In addition to sending out messages generated in other Nexus blocks, the NPC can also output the device
ID message contained in the device ID register and the port replacement output message on the MDO pins.
The device ID message can also be sent out serially through TDO.
Table 37-9 describes the device ID and port replacement output messages that the NPC can transmit on the
