TEMPTY
THIR.2
Transmit FIFO Empty. A real–time bit that is set high when
the FIFO is empty.
TFULL
THIR.1
Transmit FIFO Full. A real–time bit that is set high when the
FIFO is full.
TUDR
THIR.0
Transmit FIFO Underrun. Set when the transmit FIFO
unwantedly empties out and an abort is automatically sent.
NOTE:
The TUDR bit is latched and will be cleared when read.
