Description
Frame Transmission Complete
Indicates, in combination with the TC[0] bit, that all the
data specified by the transmit descriptor has been
transmitted from the E-MAC. This bit is set to 1 on
assuming the completion of transmission. This is when
transmission of one frame is completed and the
transmit descriptor valid bit (TACT) of the next transmit
descriptor not being set in single-frame/single-
descriptor operation or when the last data of a frame
has been transmitted and the transmit descriptor valid
bit (TACT) of the next descriptor not being set in multi-
buffer frame processing based on single-frame/multi-
descriptor operation. After frame transmission has
completed, the E-DMAC writes the transmission status
back to the relevant descriptor.
TC[1:0]
00: Transmission has not completed, or no
11: Transmission has completed
Others: Setting disabled
Transmit Underflow Frame Write-Back Complete
0: Write-back has not completed for the frame causing
1: Write-back has completed for the frame causing
Receive Overflow Frame Write-Back Complete
0: Write-back has not completed for the frame causing
1: Write-back has completed for the frame causing
Transmit Abort Detect
Indicates that the E-MAC aborts transmitting a frame
because of failures during frame transmission.
0: Frame transmission has not been aborted or no
1: Frame transmission has been aborted
