THE
TDC1.7
Transmit HDLC Enable.
0 = disable HDLC controller (no data inserted by HDLC
controller into the transmit data stream)
1 = enable HDLC controller to allow insertion of HDLC data
into either the Sa position or multiple DS0 channels as defined
by TDC1 (see bit definitions below).
Transmit Sa Bit / DS0 Select. This bit is ignored if TDC1.7 is
set to zero.
0 = route Sa bits from the HDLC controller. TD0 to TD4
defines which Sa bits are to be routed. TD4 corresponds to
Sa4, TD3 to Sa5, TD2 to Sa6, TD1 to Sa7 and TD0 to Sa8.
1 = route DS0 channels from the HDLC controller. TDC1.5 is
used to determine how the DS0 channels are selected.
DS0 Selection Mode.
Not applicable for the DS21FT40. Should be cleared to zero.
