Name/Description
Status Word on Receive FIFO.
The HDLC receiver module asserts this bit whenever
there is a status word in the receive FIFO.
0: No status word.
1: Status word.
Number of Bytes Until Next Status Word
. These bits indicate how many bytes are
present in the receive FIFO. If SWRF (bit 7) is equal to 1, indicating that a status word is
available in the FIFO, then NBNSW[6:0] indicates the number of bytes in the receive
FIFO up to and including the status byte. If SWRF is equal to 0, indicating that no status
words are available in the FIFO, then NBNSW[6:0] indicates the total number of data
bytes in the receive FIFO.

HDLC Transmit Data.
Data to be transmitted is written to this register, which maps into
the transmit FIFO. The last byte of each packet must be written to register HTXL (see
Table 62).
