TEMPTY
THIR.2
Transmit FIFO Empty. A real–time bit that is set high when the FIFO
is empty.
TFULL
THIR.1
Transmit FIFO Full. A real–time bit that is set high when the FIFO is
full.
TUDR
THIR.0
Transmit FIFO Under-run. Set when the transmit FIFO empties out
without the TEOM control bit being set. An abort is automatically sent.
NOTE:
The TUDR bit is latched and will be cleared when read.

RHS
RDC1.7
Receive HDLC source
0 = Sa bits defined by RCR2.3 to RCR2.7.
1 = Sa bits or DS0 channels defined by RDC1 (see bits defined below).
RSaDS
RDC1.6
Receive Sa Bit / DS0 Select.
0 = route Sa bits to the HDLC controller. RD0 to RD4 defines which Sa
bits are to be routed. RD4 corresponds to Sa4, RD3 to Sa5, RD2 to Sa6,
RD1 to Sa7 and RD0 to Sa8.
