This register contains the lower bits of the 64-bit descriptor base address. The lower
four bits are ignored. The transmit descriptor base address must point to a 16-byte
aligned block of data.
This register’s address has been moved from where it was located in previous devices.
However, for backwards compatibility, this register can also be accessed at its alias
offset of 0x00420.
Transmit Descriptor Base Address High - TDBAH (0x03804 +
n*0x100[n=0..1]; RW)
This register contains the upper 32 bits of the 64-bit descriptor base address.
This register’s address has been moved from where it was located in previous devices.
However, for backwards compatibility, this register can also be accessed at its alias
offset of 0x00424.
Transmit Descriptor Length - TDLEN (0x03808+ n*0x100[n=0..1];
RW)
This register contains the descriptor length and must be 128-byte aligned.
This register’s address has been moved from where it was located in previous devices.
However, for backwards compatibility, this register can also be accessed at its alias
offset of 0x00428.
Transmit Descriptor Head - TDH (0x03810 + n*0x100[n=0..1]; RW)
This register contains the head pointer for the transmit descriptor ring. It points to a
16-byte datum. Hardware controls this pointer. The only time that software should
write to this register is after a reset (hardware reset or CTRL.RST) and before enabling
the transmit function (TCTL.EN).
