FRM_HTFUNC[1:0]
Transmit Data Function. These two bits indicate the
action to be taken by writing this register:
00 = add DATA to the Tx FIFO (non-EOP).
01 = add DATA to the Tx FIFO as EOP data (i.e., last byte of
packet).
10 = abort last incomplete data packet in FIFO. (If written after
an EOP byte, this may abort the previous packet.)
11 = reserved.
7:0
FRM_HTDATA[7:0]
Transmit Data Register. When FRM_HTFUNC[1:0] = 00
or 01, then these bits contain a byte of data to be written to
the FIFO.

the number of bytes available to be filled in the Tx
FIFO for the specific channel.

00000
binary) the time-slot number assigned to this channel.

FRM_RBIT_IM[7:0]
Received HDLC Bit Assignment. These bits indicate
which bits of a time slot are to be assigned to this channel
(1 = bit assigned).

Receive HDLC Frame Select. These bits are encoded to
select odd and/or even numbered frames assigned to this
channel.
000
00 = no data selected. (Use for loopback mode.)
01 = data from even frames selected (Fs, FAS).
10 = data from odd frames selected (FT, NOTFAS, ESF-DL).
11 = data from all (even and odd) frames selected.
Reserved. Must write to 0.
