Table 6–79. Port 0 Packet Capture 2 CSR—Offset: 0x354
Field Bits Access Function Default
CAPTURE_2 [31:0] RO
Contains the ninth through twelfth bytes of the packet, if the
INFO_TYPE
field of the Port 0 Attributes Capture CSR has
the value of 3’b000 (Packet).
32'h0
Table 6–80. Port 0 Packet Capture 3 CSR—Offset: 0x358
Field Bits Access Function Default
CAPTURE_3 [31:0] RO
Contains the thirteenth through sixteenth bytes of the packet if the
INFO_TYPE
field of the Port 0 Attributes Capture CSR has
the value of 3’b000 (Packet).

Table 6–81. Port 0 Error Rate CSR—Offset: 0x368
Field Bits Access Function Default
ERR_RATE_BIAS [31:24] RW
Specifies the rate at which the ERR_RATE_COUNTER field is
decremented. This field supports the following valid values:
8’h00: Do not decrement the error rate counter.
8’h01: Decrement every 1 ms (±34%).
8’h02: Decrement every 10 ms (±34%).
8’h04: Decrement every 100 ms (±34%).
8’h08: Decrement every 1 s (±34%).
8’h10: Decrement every 10 s (±34%).
8’h20: Decrement every 100 s (±34%).
8’h40: Decrement every 1000 s (±34%).
8’h80: Decrement every 10,000 s (±34%).
All other values are reserved.
8'h0
RSRV [23:18] RO Reserved. 6'h0
ERR_RATE_RECOVERY [17:16] RW
Specifies the additional incrementing of the ERR_RATE_COUNTER
that is allowed beyond the current value of the Error rate failed
threshold trigger (ERR_RATE_FAILED_THRESHOLD field of the
Port 0 Error Rate Threshold
CSR ( Table 6–82 ). This field
supports the following values:
2’b00: Can increment 2 errors about the specified threshold.
2’b01: Can increment 4 errors above the specified threshold.
2’b10: Can increment 16 errors above the specified threshold.
2’b11: Do not limit incrementing the error rate count.
2’b11
PEAK_ERR_RATE [15:8] RW
The highest value attained by the ERR_RATE_COUNTER field since
the ERR_RATE_COUNTER field was last reset.
8'h0
ERR_RATE_COUNTER [7:0] RW
Lower bound on the number of Physical layer errors that have
been detected by the IP core, counting the errors enabled by the
Port 0 Error Rate Enable
CSR, saturated according to the
ERR_RATE_RECOVERY mechanism, and decremented by the
ERR_RATE_BIAS mechanism. This counter increments once for
every clock cycle in which at least one Physical layer error is
detected by the IP core. Provides an indication of the Physical
layer error rate.
