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.
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.

FRM_RTIMESLOT[4:0]
Received HDLC Time Slot.
These bits indicate (in
binary) the time slot number assigned to this channel.
FRM_RBIT_IM[7:0]

These bits indicate
which bits of a time slot are to be assigned to this
channel (1 = bit assigned).

FRM_RFRAME_
SEL[1:0]
Receive HDLC Frame Select.
These bits are encoded to
select odd and/or even numbered frames assigned to this
channel.
00 = No data selected. (Use for loopback mode.)
01 = Data from even frames selected (Fs, FAS).
10 = Data from odd frames selected (F
T
, NOTFAS, ESF-DL).
11 = Data from all (even and odd) frames selected.
Reserved.
Must write to 0.
Receive HDLC Link Select.
These bits indicate (in binary)
the link number assigned to this channel.
