Tx Status (TXSTA)
TXINTR: Interrupt on Transmit
Set if transmission of packet causes an interrupt condition. It includes TXCP.
DEF: Transmit deferred
Set when MAC has to defer, if MAC is ready to transmit a frame, because the carrier sense input is
asserted before the MAC gets granted to acquire the network media.
TXCP: Transmission Completion
Set when MAC completes a transmission or discard one packet.
EXDEF: Exceed Deferral
Set if MAC deferring time to transmit exceeds 0.32768ms for 100Mbit/s or 3.2768ms for 10Mbit/s.
NCS: No Carrier Sense Error
Set if carrier sense is not detected during the entire transmission of a packet..
TXABT: Transmission Abort
Set if transmitting aborted because 16 collisions occurred in the same packet.
LC: Late Collision
Set if there is collision occurs after 64 bytes collision window.
TXHA: Transmission halted
Transmission halted by clearing TXON bit in the MCMDR.
PAU: Paused
Transmit is paused by a remote flow control command.
SQE: SQE error
After transmitting a frame, set if the fake collision signal did not come from the PHY for 1.6 µs.
CCNT: Transmit Collision Count
Count of collisions during transmission of a single packet. After 16 collisions, CCNT is 1111, and TXABT
is set.
