The 7-wire serial mode interface (RCR[MII_MODE] cleared) is generally referred to as AMD mode.
Table 17-36
17.5.7
The Ethernet transmitter is designed to work with almost no intervention from software. After
ECR[ETHER_EN] is set and data appears in the transmit FIFO, the Ethernet MAC can transmit onto the
network. The Ethernet controller transmits bytes least significant bit (lsb) first.
When the transmit FIFO fills to the watermark (defined by TFWR), MAC transmit logic asserts
FEC_TXEN and starts transmitting the preamble (PA) sequence, the start frame delimiter (SFD), and then
the frame information from the FIFO. However, the controller defers the transmission if the network is
busy (FEC_CRS is asserted). Before transmitting, the controller waits for carrier sense to become inactive,
then determines if carrier sense stays inactive for 60 bit times. If so, transmission begins after waiting an
additional 36 bit times (96 bit times after carrier sense originally became inactive). See
