Transmit FIFO Empty. A real–time bit that is set high
when the FIFO is empty.
Transmit FIFO Full. A real–time bit that is set high when
the FIFO is full.
Transmit FIFO Underrun. Set when the transmit FIFO
unwantedly empties out and an abort is automatically sent.
Send BOC. Rising edge triggered. Must be transitioned
from a 0 to a 1 transmit the BOC code placed in the BOC0 to
BOC5 bits instead of data from the HDLC controller.
Transmit HDLC & BOC Controller Enable.
0 = source FDL data from the TLINK pin
1 = source FDL data from the onboard HDLC and BOC
controller
