MAC Counter Test
When set, TX and RX counters that normally clear to 0 when read, will be
set to 7FFF_FFFCh when read with the exception of the
Receive Packet Length Count Register
MAC Transmit Packet Length Count Register
and
(MAC_RX_GOODPKTLEN_CNT_x)
7FFF_FF80h.
IFG Config
These bits control the transmit inter-frame gap.
IFG bit times = (IFG Config *4) + 12
TX Pad Enable
When set, packets shorter than 64 bytes are padded with zeros if needed
and a FCS is appended. Packets that are 60 bytes or less will become 64
bytes. Packets that are 61, 62, and 63 bytes will become 65, 66, and 67
bytes respectively.
TX Enable
When set, the transmit port is enabled. When cleared, the transmit port is
disabled.
Port x MAC Transmit Configuration Register (MAC_TX_CFG_x)
This read/write register configures the transmit packet parameters of the port.
