deviceID [23:16] RW Port-write target device ID. 8'h0
LARGE_TRANSPORT [15] RW
Specifies the correct device ID size for a Maintenance port-write
transaction to report errors to a system host:
1’b0: Use the small transport device ID.
1’b1: Use the large transport device ID.

RSRV [14:0] RO Reserved. 15'h0
Table 6–72. Port-Write Target Device ID CSR—Offset: 0x328 (Part 2 of 2)
Field Bits Access Function Default
Table 6–73. Packet Time-to-Live CSR—Offset: 0x32C
Field Bits Access Function Default
TIME_TO_LIVE [31:16] RW
Maximum time duration that a packet is allowed to remain in a
switch device, where the value of 0xFFFF indicates 100 ms ±34%.
The RapidIO II IP core does not use the contents of this field. The
field value is available on the time_to_live output signal.

RSRV [15:0] RO Reserved. 16'h0
Table 6–74. Port 0 Error Detect CSR—Offset: 0x340 (Part 1 of 2)
Field Bits Access Function Default
RSRV [31] RO Reserved for this implementation. 1'h0
RSRV [30:24] RO Reserved. 7'h0
RSRV [23] RO
Reserved for this implementation. The RapidIO II IP core
does not support the Parallel RapidIO protocol.
1'h0
Received corrupt
control symbol
[22] RW Received a control symbol with a bad CRC value. 1'h0
Received ACK control
symbol with unexpected
ackID
[21] RW
Received a packet-accepted or packet-retry control
symbol with an unexpected ackID.
1'h0
Received
packet-not-accepted
control symbol
[20] RW Received a packet-not-accepted control symbol. 1'h0
Received packet with
unexpected ackID
[19] RW
Received a packet with an unexpected ackID value — an
out-of-sequence ackID.
1'h0
Received packet with
bad CRC
[18] RW Received a packet with a bad CRC value. 1'h0
Received packet
exceeding max size
[17] RW
Received a packet that exceeds the maximum allowed
size. For MAINTENANCE packets, the maximum allowed
size is 78 bytes. For non-Maintenance packets, the
maximum allowed size is 276 bytes.
1'h0
Received illegal or
invalid character
[16] RW
Received an 8B10B code group that is invalid (has no
decode with the current running disparity) or illegal (valid
code group not allowed by the RapidIO protocol), When
this bit is set, bit [2], Delineation error, is also set.
1'h0
Received data character
in IDLE1 sequence
[15] RW
Reserved for this implementation, The RapidIO II IP core
does not support the IDLE1 sequence.
