4.3.2.5 Resume Packet
The reception of the resume packet, shown in Figure 48, causes any node to resume operations for all PHY ports
that are both connected and suspended. This is equivalent to setting the resume variable TRUE for each of these
ports. The resume packet is a broadcast packet, there is no reply. Field descriptions for the resume packet are shown
in Table 47.

Asynchronous Receive FIFO (ARF)
Asynchronous receive refers to the use of the ARF interface. It is configurable in register 30h (ARF status register).
The ARF receives the response of packets transmitted from the ATF. The ARF also receives request packets from
other nodes, except packets meant for the agent. The received packets are stored in ARF FIFO in the format
described below. The host accesses the packets in the ARF through register 80h.
4.4.1
Generic Quadlet and Block Receive
The quadlet-receive format is shown in Figure 49. The first quadlet is a packet token and contains packet-control
information. The first 16 bits of the second quadlet contain the destination bus and node number, and the remaining
16 bits contain packet-control information. The first 16 bits of the third quadlet contain the bus and node number of
the source, and the unreserved 4 bits of the third quadlet contain packet-control information. The fifth quadlet contains
data that was used by write requests and read responses. For read requests and write responses, the quadlet data
field is omitted.

Figure 49. Generic Receive Format of Packet With Quadlet Data
The block-receive format is shown in Figure 410 and field descriptions are shown in Table 48. The first quadlet is
a packet token and contains packet-control information. The first 16 bits of the second quadlet contain the bus and
node number of the destination node, and the last 16 bits contain packet-control information. The first 16 bits of the
third quadlet contain the bus and node number of the source node, and the last 16 bits of the third quadlet and all
of the fourth quadlet contain the 48-bit, quadlet-aligned destination offset address. All remaining quadlets contain
data that is used only for write requests and read responses. For block read requests and block write responses, the
data field is omitted.
