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).
TSaDS
TDC1.6
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.
TDS0M
TDC1.5
DS0 Selection Mode.
0 = utilize the TD0 to TD4 bits to select which single DS0 channel to use.
1 = utilize the TCHBLK control registers to select which DS0 channels to
use.
TD4
TDC1.4
DS0 Channel Select Bit 4. MSB of the DS0 channel select.
TD3
TDC1.3
DS0 Channel Select Bit 3.
TD2
TDC1.2
DS0 Channel Select Bit 2.
TD1
TDC1.1
DS0 Channel Select Bit 1.

TDC2.1
DS0 Bit 2 Suppress Enable. Set to one to stop this bit from being used.
TDB1
TDC2.0
DS0 Bit 1 Suppress Enable. LSB of the DS0. Set to one to stop this bit
from being used.
