TLINK
Link Address in Transmit Buffer Address 2
When set, it indicates that Transmit Buffer Address 2(T03) contains the start
address of the next descriptor of the descriptor list. Otherwise the T03 is used to
point to the start address of the transmit buffer 2 when the TLINK is reset. The
TLINK is valid on each descriptor.
23
PD
Padding Disable:
The W89C840F does not add the padding data on a frame shorter than 64 bytes
when the PD bit is set to high. However, the W89C840F will automatically add a
padding data on a frame shorter than 64 bytes when the PD bit is reset to low.
The four bytes of CRC will be appended at the end of the padding field of the
transmitted frame no matter what the ICRC is set or reset if the PD is reset.
The total transmited frame data length will be 68 bytes if the data in the current
frame is less than 64 bytes and the PD is reset. This bit is valid only when TFD
(T01[29]) is set.
21:11
TSZ2
Transmit Buffer 2 Size:
The TSZ2 indicates the size, in bytes, of the second data buffer pointed by the
current transmit descriptor. If this field is 0, the W89C840F will ignore this
buffer. The TSZ2 value is valid on each descriptor.
10:0
TSZ1
Transmit Buffer 1 Size:
The TSZ1 Indicates the size, in bytes, of the first data buffer pointed by the
current transmit descriptor. If this field is 0, the W89C840F will ignore this
buffer. The TSZ1 value is valid on each descriptor.
T02, Transmit Descriptor 2
The T02 is used to specify the start address of the transmit buffer 1
Bit

Description
31:0
TBA1
Transmit Buffer Address 1
The TBA1 indicates the physical address, in the system memory space, of the
first transmit buffer pointed by the current descriptor. The TBA1 allow to be
programmed with any value by the driver program. It is valid on each descriptor
of the current frame.
T03, Transmit Descriptor 3
The T03 is used to specify the start address of the transmit buffer 2
Bit

Description
31:0
TBA2
Transmit Buffer Address 2
The TBA2 indicates the physical address, in the system memory space, of the
second transmit buffer pointed by the current descriptor. The TBA2 allow to be
programmed with any value by the driver program. It is valid on each descriptor
of the current frame.
