The statistics for the frame transmitted are contained within the tx_statistics_vector output. The bit field definition for the Vector is defined in Table 4. All bit fields, except BYTE_VALID, are valid only when the tx_statistics_valid is asserted, as illustrated in the following figure. BYTE_VALID is significant on every transmitter cycle that the clock enable is High. tx_statistics_vector bits 28 down to 20 inclusive are for half-duplex only and are set to logic 0 when operating in full-duplex mode.
