Write an “1” to TXQCR[0] reg to issue a

Option to Read ISR[14] reg, it indicates
that the TXQ has completed to transmit
This is moving transmit data from Host
upper layer and prepares transmit pkt
to the TXQ. The TXQ will transmit this
write transmit data (control word, byte
transmit command (manual-enqueue)
at least one pkt to the PHY port, then
count and pkt data) to TXQ memory.
Write an “0” to RXQCR[3] reg to end
data (data, data_length, frame ID).
The transmit queue frame format is
Host receives an Ethernet pkt from
TXQ write access, then Host starts
