These Bits Define the Position of the Last Byte to be
Transmitted from the Buffer.
Reserved.
If M13_DS2_LB_REQy = 1, the Third C Bit in the yth DS3
M-Subframe is Transmitted as the Inverse of the First Two
C Bits (Which Indicates a Loopback Request for DS2
Channel y).
Reserved.
One Byte from HDLC Buffer 0 are Transmitted. If it is 1,
bytes from buffer 1 are transmitted sequentially up to and
including the byte set by M13_TDL_BYTE_END[5:0]
(Table
One Byte from HDLC Buffer 1 are Transmitted. If it is 1,
bytes from buffer 0 are transmitted sequentially up to and
including the byte set by M13_TDL_BYTE_END[5:0].
If the Data Link is not Used, the User Should set
M13_TDL_ACT to 0, Which Causes all Ones to be Trans-
mitted. Otherwise, this bit should be set to 1.
If M13_TDL_NTRNL = 0, the Data Transmitted on the
Data Link Comes Directly from the M13 Input Pin TDL-
DATA (E8); Otherwise (M13_TDL_NTRNL = 1), the Data
Link is Controlled by the Internal HDLC Transmitter. This
bit is valid only when M13_TDL_ACT = 1
Transmitter Begins Transmitting the First Byte of the
First Data Buffer Following the Completion of the Next
Flag Byte. The user may abort the transmission of an HDLC
frame by clearing M13_TDL_NTRNL_ACT to 0 prior to com-
pleting transmission of the last byte from the data buffers. If
so, the HDLC controller will stop transmission from the buff-
ers and send an abort byte (01111111). The abort byte will
then be followed by flag bytes until M13_TDL_NTRNL_ACT
is again set to 1, starting transmission of a new frame.
If M13_TDL_FCS = 1, the HDLC Controller Appends the
Two-Byte ITU-T FCS with the Necessary Zero Stuffing
Before Sending the Closing Flag; Otherwise, no FCS
Bytes will be Transmitted.
