Table 6–76. Port 0 Attributes Capture CSR—Offset: 0x348
Field Bits Access Function Default
INFO_TYPE [31:29] RO
Indicates the type of information logged. The RapidIO II IP core
supports only the following valid values for this field:
3’b000: Packet.
3’b011: Long control symbol.
3’b100: Implementation specific.
3'h0
ERROR_TYPE [28:24] RO
The encoded value of the bit in the Port 0 Error Detect CSR
that describes the error captured in the Port 0
Packet/Control Symbol Capture 0–3
CSRs.
The encoding is 31 minus the binary number that represents the
bit position in the CSRs.
5'h0
IMPL_DEPENDENT [23:8] RO
The RapidIO II IP core uses this field as recommended in the
RapidIO v2.2 specification.
If the value of the INFO_TYPE field is 3’b000, indicating a packet,
this field captures the control bits of the first 16 packet
characters.
If the value of the INFO_TYPE field is 3’b011, indicating a long
control symbol, bits [23:16] of this field capture the eight control
bits of the delimited long control symbol.
If the value of the INFO_TYPE field is 3’b100, indicating
implementation-specific information, this field is undefined.
16'h0
RSRV [7:1] RO Reserved. 16'h0
CAPTURE_VALID_INFO [0] RW
Indicates that the Port 0 Packet/Control Symbol Capture
0–3
CSRs, and the other bits in the Port 0 Attributes
Capture CSR contain valid information and are locked. To reset
this bit and unlock the other fields in this register, you must write
the value of 1’b0 to the CAPTURE_VALID_INFO bit.
If INFO_TYPE is 3’b011, Long control symbol, only the Port 0
Packet/Control Symbol Capture 0 CSR
has valid
information when these registers are locked. If INFO_TYPE is
3’b100, Implementation specific, none of these registers has
valid information when they are locked. However, the
CAPTURE_VALID_INFO
bit is asserted when the registers are
locked.
16'h0
Table 6–77. Port 0 Packet/Control Symbol Capture 0 CSR—Offset: 0x34C
Field Bits Access Function Default
CAPTURE_0 [31:0] RO
Contains the first four bytes of the packet or long control symbol,
based on the INFO_TYPE field of the Port 0 Attributes
Capture
CSR.
32'h0
Table 6–78. Port 0 Packet Capture 1 CSR—Offset: 0x350
Field Bits Access Function Default
CAPTURE_1 [31:0] RO
Contains the fifth through eighth bytes of the packet or long
control symbol, based on the INFO_TYPE field of the Port 0
Attributes Capture
CSR.
