Receive Packet Unicast Statistics Counter (RX_PKT_UNICAST)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-64. Receive Packet Unicast Statistics Counter Description
Packets Received Statistics Counter (RX_PKT_RCVD)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-65. Packets Received Statistics Counter Description
Receive Packet 64 With Good CRC Statistics Counter (RX_PKT_64_GOOD_CRC)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-66. Receive Packet 64 With Good CRC Statistics Counter Description
Receive Packet 1518 With Good CRC Statistics Counter (RX_PKT_1518_GOOD_CRC)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
