Carrier_sense_errors 0x068
Bits Data Element Name R/W
Reset
Value
Description
[31:8] Reserved - 0x0 Must be set to zero
[7:0] Carrier_sense_errors R/W 0x0 An 8-bit register counting the number of packets
transmitted where carrier sense was not seen during
transmission or where carrier sense was deasserted after
being asserted in a transmit packet without collision (no
underrun). Only incremented in half-duplex mode. The
only effect of a carrier sense error is to increment this
register. The behavior of the other Ethernet MAC counters
is unaffected by the detection of a carrier sense error.
Rx_symbol_errors 0x074
Bits Data Element Name R/W
Reset
Value
Description
[31:8] Reserved - 0x0 Must be set to zero
[7:0] Rx_symbol_errors R/W 0x0 An 8-bit register counting the number of packets that had
MII_RX_ERR
asserted during reception.
Excessive_length_errors 0x078
Bits Data Element Name R/W
Reset
Value
Description
[31:8] Reserved - 0x0 Must be set to zero
[7:0] Excessive_length_packets R/W 0x0 An 8-bit register counting the number of packets received
exceeding 1518 bytes in length (2000 if
Rx_2000_byte_packets is set in the
4MAC_network_configuration register) but do not have a
CRC error, an alignment error nor a Rx symbol error.
Rx_jabbers 0x07C
Bits Data Element Name R/W
Reset
Value
Description
[31:8] Reserved - 0x0 Must be set to zero
[7:0] Rx_jabbers R/W 0x00 An 8-bit register counting the number of packets received
exceeding 1518 bytes in length (2000 if
Rx_2000_byte_packets is set in the
4MAC_network_configuration register) and have either a
CRC error, an alignment error or a Rx symbol error.
Undersize_packets 0x080
Bits Data Element Name R/W
Reset
Value
Description
[31:8] Reserved - 0x0 Must be set to zero
[7:0] Undersize_packets R/W 0x0 An 8-bit register counting the number of packets received
less than 64 bytes in length, that do not have either a
CRC error or an alignment error.
