| I'd like to ask two questions that have nothing to do with the code. 1.I can get to know which mode,half duplex or full duplex,the mac is working on only through reading the status register, is it right? 2.If the mac is going to send a package while it is working on halfduplex mode, is it only when the rx_en is at low level can mac deliver the package to PHY ? and also only tx_en is at low level can mac receive a package? Thanks for your reply. Regards, lxn ============================================================= 用vip邮箱，送《求职宝典》！ 10元钱能做什么？安全稳定，尽在网易VIP邮箱！ 有手机就有网易VIP邮箱！ 网易VIP邮箱，打个电话立即拥有！ "V"：展现自我，体味信心！ |
