DP83TG720R-Q1: 芯片的Tx_err_pkt_cnt寄存器0x063B

Part Number: DP83TG720R-Q1

Hi 

在TI的《 DP83TG720 : Counting Packets and Errors》文档中提到了一组寄存器,可以用来检查PHY内部的Packets计数情况;

其中,0x639、0x63A、0x63B均为TX 的Counter;

请问这里的TX Counter的数据来自哪一方向?MDI的PMA/PCS?还是RGMII的MAC TX?

如果来源是MDI的PCS/PMA的话,PHY芯片是如何监测的其输出数据的error packet?

此外,这里的TX Counter是否需要配置寄存器来使能?
