Table 34 Port 0 Control CSR
Re-transmit Suppression Mask:
Suppress packet re-transmission on CRC error.
SerB does not support this feature and these bits are set to zero.
Reserved.
Enumeration Boundary:
An enumeration boundary aware system enumeration algorithm
shall honor this flag. The algorithm, on either the ingress or the
egress port, shall not enumerate past a port with this bit set. This
provides for software enforced enumeration domains within the RIO
fabric.
Flow Control Participant, enable flow control transactions:
1b0 - Do not route or issue flow control transactions to this port
1b1 - Route or issue flow control transactions to this port.
(RIO spec. Part 9, sec. 4.3)
Multicast-event Participant:
This bit is hard-wired to 0.
Error Checking Disable, this bit disables all RIO transmission error
checking:
1b0 - error checking and recovery is enabled
1b1 - error checking and recovery is disabled
Input Port Enable, input port receive enable:
0b0 - port is stopped and only enabled to route or respond to I/O log-
ical MAINTENANCE packets.
0b1 - port is enabled to respond to any packet.
Output Port Enable, output port transmit enable:
1b0 - port is stopped and not enabled to issue any packets except to
route or respond to I/O Logical Maintenance packets.
1b1 - port is enabled to issue any packets.
Port Disable:
1b0 - Port receiver/drivers are enabled
1b1 - Port receivers/drivers are disabled and are unable to receive/
transmit any packets or control symbols
Port Width Override, soft port configuration to override the hardware
size:
3b000 No override
3b001 Reserved
3b010 Force single lane, lane 0
3b011 Force single lane, lane 2
3b100 - 3b111 Reserved
The change of this field during normal mode may cause re-initializa-
tion.
Initialized Port Width, width of the ports after initialized (read-only):
3b000 Single-lane port, lane 0
3b001 Single-lane port, lane 2
3b010 Four-lane port
3b011 - 3b111 Reserved.
Port Width, hardware width of the port (read-only):
2b00 Single-lane port
2b01 Four-lane port
2b10 - 2b11 Reserved.
