8.4.3MAC TX Statistics Register Overview

The MAC TX Statistics registers contain all the MAC transmit statistic counters and are cleared when read. The software must poll these registers to accumulate values and to ensure that the counters do not wrap. The 32-bit counters wrap after approximately 30 seconds.

Table 94 covers all four MAC ports TX statistics. Port_Index is the port number (0, 1, 2, or 3).
