NAME AND DESCRIPTION
NAME AND DESCRIPTION
Not Assigned. Could be any value when read.
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.
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 on-board HDLC and BOC
controller
BOC Bit 5. Last bit transmitted of the 6-bit codeword.
BOC Bit 4.
BOC Bit 3.
BOC Bit 2.
BOC Bit 1.
BOC Bit 0. First bit transmitted of the 6-bit codeword.
